This is a class project that is an attempt at procedural maze generation. I have several simple pieces that I modeled in Maya that snap together. I hope to further develop this algorithm as it has been rather challenging but also fun to work on. It is still a work in progress and if I get a final build working I will post it here as well. You can reset with the R button, it make take a few minutes for the maze to appear and there is no camera movement so the maze may go off screen.

Your algorithm seems a bit slow, you could show a "generating" screen whilst it's working, also try to keep the maze within the limits of the screen
