  He’s working for a childrens’ museum, so how much less fun would that be?! =]

    I missed that part — you’re totally right! I can imagine half the fun is trying to get things where you want them, and having that not work :) Maybe magnets would be easier than tape? I’m curious to see what his final synth looks like.

      Thanks! Yeah, my actual plan for this is to make a larger wheel out of steel and use brightly colored magnets, but wood is much easier to manufacture for a prototype :-).

        I was about to suggesting to get rid of magnets placing the wheel horizontally, when I suddenly realized how similar it would be to a merry-go-round.
        It should fairly easy to place te webcam on top of the carousel and change the software to detect children’s positions.
        I can’t wait to see how chldren react to the thing!
