Every now and then I stumble on something rather clever whilst taking a daily tour of the web. This weeks find is this Twitter marble run. It allows anyone using Twitter to interact with the run, releasing marbles in real time and watching it live on the camera feeds - all you need to do is tweet the hash tag “#marbleart.tv” to release a marble.

Its a really simple idea but one which has great potential. I’m thinking we’re going to be seeing ideas like this as more creative people start to fuse the virtual and real world together.
