What is Constellation?
A night sky full of stars, waiting to be joined up. As you move in front of the camera you leave a slowly fading trail behind you, and any two stars the trail passes between link together with a faint glowing line — so drawing a shape with an arm turns a scatter of dots into a constellation. The lines fade after a few seconds, which means the sky keeps clearing itself and there is never a wrong answer. No score, no timer, nothing to lose. It makes a good bedtime-ish scene, and a good way into talking about the real constellations, because the pattern is one the child invented rather than one they were handed.
