I had invented three dimensional tic-tac-toe. Naughts and crosses for other parts of the world. Twenty seven boxes in the shape of a cube. One side had green balls and another had brown balls. What was interesting about the invention is that the box was self-aware and could alter the game at will. It wasn't a computer just a bunch of machines which were able to do the same kind of computation and rationalization of a human brain. When I presented the device everyone pooh-poohed it since it was just a machine rather than meeting their particular criteria for a sentient mind. Towards the end of the dream I started to feel stupid from everyone's derision and the fact that I really didn't assemble the device. Instead the device hinted to me how it should be cobbled together to accomplish my goal.
