Light Year Delay
A mobile chat toy where messages to eight real cosmic correspondents, from the Moon to Proxima Centauri, travel at true light-speed on a compressed clock. Pick a correspondent, send a message, watch a light pulse cross the true relative distance, and receive an authored reply timed to the honest round trip. A real-time toggle shows genuine Moon/Mars delay in real seconds. Finish with a shareable result card.
