Tweet "@textstats punctuation" for your percentile scores as regards how frequently you use commas, semicolons, and so forth. It transpires that I use more commas that 93% of the English-speaking population of Twitter, which, frankly, isn't too surprising.

They are holding an art auction tonight in the amazing surrounds of <a href="http://www.locationhouse.co.uk/the_dairy/index.html">the Old Dairy</a> (WC1N), with all proceeds contributing towards environmental causes. I have a framed photograph in the show, <i>Untitled (Isle of Grain)</i>. <img src="http://www.erase.net/images/weblog/stitch-photo.jpg" class="image" /> <p class="caption">Untitled (Isle of Grain), C-type 35mm print, 60cm x 42cm, 2011</p> I have written a short piece of text explaining the background to the image. <blockquote><p>The Isle of Grain is a region of marshland in the north of Kent, at the mouthway of the River Thames. In virtue of its astounding biodiversity and variety of habitats, it is classified by ecologists as an "open mosaic" environment, home to a rich tapestry of wildlife. Thirteen of its native species are endangered with extinction, with a further 34 classified as nationally scarce. It is home to Britain's rarest species of native bee.</p><p>Its sparse populous, coastal location and proximity to London also make the Isle of Grain a target for industrial development. Formerly home to a BP oil refinery, it is now occupied by the Thamesport container seaport, an oil-burning power station, a Liquefied Natural Gas import facility, and the landing point of the BritNed high-voltage submarine power cable, linking Kent with Maasklakte, Holland. A further gas-fired power station is planned by the National Grid, who own over 700 acres of the surrounding land. </p><p>In November 2011, Lord Norman Foster presented a proposal to develop Grain as the radial point of a new high-tech transport system, the "Thames Hub". This would include a four-runway airport with twice the capacity of Heathrow, a Trade Spine to link utility pipes and cables to the north of England, and a high-speed rail station, forecast to become the UK's busiest.</p></blockquote> The auction also includes works by the like of Vivienne Westwood, Richard Long, Marc Quinn and Richard Wentworth. The <a href="http://www.inholborn.org/?q=node/668">event runs from 6pm</a>. Wed, 30 Nov 2011 17:49:44 GMT http://www.erase.net/weblog/2011-11/photographic-print-at-stitch-art-auction http://www.erase.net/weblog/2011-11/hearing-connections-at-the-royal-institution I'm giving a talk next week as part of the excellent-sounding <a href="http://www.rigb.org/contentControl?action=displayEvent&id=1202">Hearing Connections</a>, an evening of lectures on sonification and networks. It's part of a series of events at the <a href="http://www.rigb.org/">Royal Institution of Great Britain</a>, the 200-year-old establishment that Faraday and Medawar once called home. So, no pressure then. I'll be discussing the relationships between sound and ecosystems, giving a whistle-stop tour of emergence, nested hierarchies and complexity, via Wolfram and Stockhausen, and hopefully culminating in a demo of some exciting new multi-level simulation work that I've been developing. Here's the abstract: <blockquote>What does a concerto have in common with a coral reef? The answer is that both are made up of nested hierarchies, in which an individual on one layer contains a population of the one below. An ecosystem comprises of multiple species, each of which contains multiple communities, made up of multiple individuals -- and an individual is itself an ecosystem of organs, cells and microbes. Likewise, a concerto comprises of movements, which comprise of parts, which comprise of notes and harmonies. This talk is a brief tour around the relationships between music and ecology, and how their similarity can be used as a fruitful way to illuminate both our scientific and artistic practices. <ul><li>Can translating a real ecosystem into sound reveal hidden properties to us?</li><li>Can the dynamics of an ecosystem be thought of as creative, or teach us about creativity?</li><li>Can there be a single set of simple rules that unify all of these levels collectively?</li></ul></blockquote> Hearing Connections runs from 7pm on Tuesday 15 November.

Entitled "Maelstrom", it is a multichannel sound installation that uses real-time YouTube uploads as its raw material, using them to resynthesize morphing banks of chord sequences. These are then spun rapidly around the listener by a multichannel system of repurposed speakers, creating a tornado of audio data. From the press blurb: <blockquote>Over 48 hours of user-created audio is uploaded to the internet every minute, a figure that is increasing exponentially. <i>Maelstrom</i> is a sound installation that draws on this material in real time, constructing shifting walls of sound from thousands of audio fragments. By organising these fragments based on their tonal attributes, they collectively form a vast instrument, whose properties are affected by global internet activity. A score composed specifically for this instrument voices an endless series of chord variations, dynamically generated by an array of live processes. Maelstrom builds a tornado of tonal cluster chords around its spiral speaker system, engulfing the listener in the swirling mass of information that is now an integral part of our day-to-day lives.</blockquote> Off Modern Late is on <b>Thursday 24th November</b>, in various spaces around the Barbican Centre, from 6.30pm onwards.

For those around East London over the coming weeks, I have a digital print in the exhibition <i>Cats and Kittens</i>, opening at Barden's (N16) on 14th July. <i>Untitled (Digital Photographs, 2002-2011)</i> compresses 11,000 digital photos taken over 10 years into a single poster-sized image, incorporating a line of pixels from each in sequence. It's not reproducible online due to its large scale and detail, but can be seen from late next week (details on poster below). <img src="http://www.khankah.org/files/2011-07/poster.jpg" class="image" /> Thu, 07 Jul 2011 20:00:58 GMT http://www.erase.net/weblog/2011-07/untitled-digital-photographs-2002-2011-at-cats-and-kittens-n16 http://www.erase.net/weblog/2011-06/horizontal-transmission-2011-at-a-theory-of-everything In the culmination of a busy few weeks, I have another new digital installation opening this Friday. <i>Horizontal Transmission</i> is a semi-interactive sonic ecosystem based on bacterial dynamics, somewhere between a VR game and <i>in silico</i> systems biology simulation. It's an extension of research that I've recently been involved with in conjunction with the pioneering <a href="http://mathbio.nimr.mrc.ac.uk/">Division of Mathematical Biology</a> at the <a href="http://www.nimr.mrc.ac.uk/">National Institute for Medical Research</a>. <img src="/projects/horizontal-transmission/images/screenshot.preview.500.jpg" alt="preview screenshot" class="image" /> It's a part of <a href="http://www.artrabbit.com/events/event/26819/a_theory_of_everything">A Theory of Everything</a>, at Deptford's <a href="http://coregallery.co.uk/current-exhibition/">Core Gallery</a> from 24 June to 10 July, alongside a number of other works based on physical patterns and the empirical search for unifying scientific laws. More on the piece: <blockquote>Bacterial organisms exhibit a trait that is unique within the living world. As well as inheriting genetic properties from parent to child, bacteria are able to exchange genetic information with their neighbours, via packets of DNA known as 'plasmids'. This enables bacteria to temporarily adopt characteristics which may give them a competitive advantage in a hostile environment. Plasmids can be seen as semi-beneficial parasites which hop from bacterial host to host, giving rise to complex evolutionary patterns. "<i>Horizontal Transmission</i>" (2011) simulates these dynamics in a 3D space, representing populations of cells both visually and sonically. When sound is detected from the gallery space by the attached microphone, it is transformed into a plasmid and deposited in the virtual space. This can then be assimilated by the bacterial population, who then mimic these sounds in their inter-cellular communications. The bacterial world can be explored using a 3D control interface, with which an observer can navigate through the population, observing cellular dynamics and communication patterns.</blockquote> There are subsequently a number of informal salons featuring the artists and scientists involved.

Ordering #1 (Sans/Soleil) is a reworking of Chris Marker’s "Sans Soleil" (1983) in which the film’s frames are sorted in order of luminosity and projected as a loop. It cycles from the black frames of its opening to those of maximal brightness, and again in reverse. <img src="/images/weblog/sans-soleil-500.png" class="image" /> More information: <a fref="http://blog.apiarystudios.org/2011/06/m&#8756;m&#8756;m&#8756;/">M&#8756;M&#8756;M&#8756;</a> Tue, 07 Jun 2011 14:23:27 GMT http://www.erase.net/weblog/2011-06/ordering-1-sanssoleil-at-m8756m8756m8756-apiary-studios http://www.erase.net/weblog/2011-04/lettercloud Letters of the alphabet, scaled by frequency of occurrence in typical English text. <a href="http://www.erase.net/images/weblog/lettercloud.jpg"><img src="http://www.erase.net/images/weblog/lettercloud-500.jpg" class="image" alt="lettercloud" width="500"></a> ...and its counterpart for single-digit numbers, a numbercloud of <a href="http://en.wikipedia.org/wiki/Benford%27s_law">Benford's law</a>. <a href="http://www.erase.net/images/weblog/numbercloud.jpg"><img src="http://www.erase.net/images/weblog/numbercloud-500.jpg" class="image" alt="numbercloud width="500"></a> Clouds generated by <a href="http://wordle.net/">Wordle</a>.

Their API also provides a <a href="http://www.mailinglistarchive.com/html/twitter-development-talk@googlegroups.com/2010-09/msg00915.html">limit of 3200 historical tweets</a> per timeline, meaning that, eventually, your past posts will be inaccessible. So, in a spare moment, I created <b><a href="https://github.com/ideoforms/tweetarchive">tweetarchive</a></b>, a lightweight Python-based tool to export complete timelines in CSV. Features: <ul><li>uses the <a href="https://github.com/joshthecoder/tweepy">tweepy</a> library with oauth for protected accounts</li><li>only archives tweets created since your previous export</li><li>writes CSV output with user-specified format - so select what fields you'd like to archive</li><li>uses time delays to avoid hitting load throttling</li><li>client-side, meaning no need to give third-party apps access to your auth tokens</li></ul> <a href="https://github.com/ideoforms/tweetarchive">Download it here</a> (requires git).
