Although it isn’t really clear what happens at the start (you can see it more clearly from the middle of the video) the idea behind this machine is that a ball in the physical world rolls into the computer, is transmorgified into a new ball, which is then spit out of the computer to start the journey anew.  Twenty-Seven people made the machine work through 9 computers.

Thanks to the Scratch Ed team for organizing the workshop and giving us that one last opportunity to make it all work together!  Some say process is more important than product, but there is an undeniable feeling of exquisite joy when, after holding your breath, the whole “product” works the way it is supposed to work.
