One diamond is missing and if you find and isert it the stage begins to tell you where the next stage is (sound module). A Servo motor projects the X and RGB LEDs fade. Looks pretty cool.

It's activated by a hall sensor and wake up code. The missing diamond has a hidden magnet.

printed in white pla but this was a bad idea because it reflects to much light. Had to paint it black.
