Interesting I had not heard of Dynamicland previously. The posted project though reminds me a bit of reacTable [1] although the latter is targetted to music media creation. It's a 'product' now, I guess, but it started off as a research project published in early 2000s. I gather that Dynamicland goes back quite a bit further which is interesting. In our group we wanted to see how dead easy it would be to build an interactive projection system, so we did it.. just mounted a projector and a camera above a table [2] -- can't believe it's already been 10 years since then. It was surprisingly simple -- we didn't bother with AR tags, just used silhouettes via simple video processing as inputs to vector field operations to generate movement and influence physics simulations and audio-generating algorithms. The advantage being that you literally just stick your hand in there and something happens, it was great for kids. But building the whole system was quite easy too, it would make a great "science project" for the right age. Oh, another fun "tangible computing" project from the same era was "BeatBearing", dug up the video here... [3] There's a lot you can do with a simple camera!
