Google Maps Typewriter
If Ohio is a Piano then there's no reason why Google Maps can't be a typewriter.
This Google Maps mashup uses alphabetical glyphs found on Google Maps to create a cartographic typewriter. Just type a word into the search box and press return. You will then be shown a link on Twitter that leads to your chosen word, written using glyphs found in the satellite imagery on Google Maps.
The site also has an interesting CAPTCHA experiment using letters found on Google Maps.
My ambition now is to get two rooms of monkeys, one banging away on Google Maps Typewriter and the other on Ohio is a Piano. I think I'll have Shakespeare and Beethoven beat in no time.
