A single photon QM is basically classical wave 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_tester 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!).
