What would I do with this?

I have been spending some time looking at some robotics. Mosty from a hobbiest point of view. I ran into something cool on a blog called: Liquidware Antipasto

It is talking about modules that communicate with each other to share code. The code basically changes the color of a blinking LED. It is cool to watch the code move from module to module - changing the color of the LED as it moves.

I don't know how I would use this tech, but it looks cool. The modules are availile from http://www.liquidware.com/
