The game starts by triggering the proximity sensor at the top of the board and a random LED will light up a random colour. The same coloured laser also turns on and the clock is started at 20 seconds. When you complete the beam path to it's target, the next colour & laser is randomly selected. The remaining time on the clock adds to your score.

Past level 15 the time to solve each level is reduced. Eventually to 6 seconds. Failing to solve the puzzle in the time limit will end the game.

The top clear acrylic and lower ply pieces where cut using a laser cutter (K40). I used a vinyl cutter to cut the black and white decals placed under the clear acrylic. And finally i 3d printed the laser mounts and covers to complete the game.

NOTE: you probably shouldn't build this...laser safety and all that!
