At Maker Faire last week, my booth had the TapeScape robot on display (which I made with Ilan Schifter - made almost completely out of a tape deck, broadcasting the sound from the "scape" of "tape" it would roll over), prompting several people to mention that there was a very similar robot inside the Queens Hall of Science.
I had to check it out for myself, and had the pleasure of meeting Dan Perrone. His project is not only very similar to TapeScape in it's design and action, but has quite a similar name: TapeLake.
It turns out that we developed our projects independently of each other, but came to similar conclusions, and are both Brooklyn residents. As Dan said "We're all the same fleas on different dogs."
