Giant SL/Twitter typewriter

Now residing at The Pencil Factory, The Port. Originally created for Penguin last year, this giant typewriter publishes to Twitter. Touch to type, or sit on the keys to type in capitals. Feel free to create upto 140 characters of nonsense or poetic gems. Once you've typed it, touch the carriage return lever - to publish to - http://twitter.com/SLtypewriter and also onto the virtual paper.
