Former thinkpublic intern Jonathan Attenborough has been constructing a wonderful recycled bike art machine to raise money for greasefingers, a charity which rennovates old bicycles and donates them to people who need them in Africa.
The machine is called Spin Art, you can see it in action as well as how it was built in the short film above.

Hey guys! Thanks for the post, the Spin Art bikes are currently on a very big boat on their way to China. There they will be part of a climate change awareness exhibition, which is happening in three cities. It always amuses me to think of sending stuff to China when we are always on the receiving end.
