Thanks again for building it, it was the first time I could actually bring my mind to embracing quantum mechanics :-)
My original intention was to do many-photon QM game (and wrote game engine for that). But in development I discovered that even wave mechanics offer quite a lot interesting, and counterintuitive, puzzles.
With one photon there the only thing that does not have a classical analogues is https://en.wikipedia.org/wiki/Elitzur%E2%80%93Vaidman_bomb_t..., which can be easily assembled from the blocks (well, the idea for using a light-sensitive bomb comes from there!).
