Commercial: Crapbot

Not doing the London to Brighton cycle ride tomorrow? You can still get stuck in. Writes John Vinton:

Nine of us are cycling to Brighton on Sunday to raise money for The British Heart Foundation.

To make it more interesting, you can tweet messages to us on the way (just include #aiscycling in your tweet). We’ll jump off our bikes and chalk them on the road. And take pictures. It’s called Crapbot. A bit like Nike Chalkbot. But rubbish.

Go to Crapbot to find out more.

Writing messages on the road is a Tour de France tradition. The messages are normally inspiring. But yours can be humiliating if you prefer. More importantly, you can also donate a few quid if you like.
