So. Sitting on the “can”, and I just came up with a cool game idea!
2 scouts, each with a small NeoPixel strip, and a gyro inside a small box. Each scout is basically an egg timer, you flip it upside down and the NeoPixel strip represents a countdown. Once the countdown is started, the other player must flip their scout over to start the countdown in the other direction. Gameplay takes place over a long period of time, the looser doesn’t need to play their move immediately, so the winner doesn’t know when they may have to flip theirs again!
