Shigeru Kobayashi wrote in to tell us about this very cool project, physical x wonderfl, which is a mash up of an online IDE and physical computing. With an Arduino or Gainer board and the Funnel Server, you can connect your microcontroller board to a computer, and run your sketch from inside the browser. You can also share sketches for others to use or try out sketches that others have uploaded.

The screencast embedded above shows the steps needed to get up and running with this neat tool.
