Does exactly what it says on the tin. Takes a tweet from the Public Timeline and splices it together with a random second panel from Dinosaur Comics via Maddison Karlsdottir's script I cannot take credit for the idea, which belongs to Bing at Cakebomb , but I couldn’t see the idea not be completely fulfilled. This the generating URL.

It now caches the Public Feed, gathering 20 tweets every five minutes. This was because it was (easily) using up the 100 API requests an hour that Twitter lets you have, and so died early on in the hour before ticking over to the next one. All fixed now! Sorry if you tried it while it was not playing ball.
