Radiant Hunt
Meteors in a shower travel in parallel, so their trails all point back to one spot in the sky: the radiant. Each trail is drawn faint at its start and bright at its head. Trace them backwards and tap where they meet.

Why trails meet at a point
Stand on a long straight road and the edges appear to meet in the distance. Meteoroids in a stream move along nearly parallel paths, so as they hit the atmosphere their streaks seem to fan out from a single point, even though they appear all over the sky. Showers are named after the constellation that holds their radiant: the Orionids from Orion, the Perseids from Perseus, the Geminids from Gemini.
Scoring: 1,000 points for a perfect guess, falling to zero at 15° away. Distances are measured on the sky, not on your screen.
