Geopaint is a Google Maps mashup with the map as a canvas and your mobile phone as a brush. Geopaint periodically fetches your current location and connects the dots to create line paintings of your movements.
It is possible to change the colour and the size of your brush as you move around. As well as creating your own geoglyphs with Geopaint you can view the paintings created by others.
Although developed in Germany Geopaint is in English and whilst it was developed for mobile browsers you can access it from your desktop computer.
