Last year Kyle Thiessen created a series of "fake month at the museum" five-minute short films that explore different odd facts from history and the natural world. I've just started watching these, and I'm totally hooked. Whatever you do, don't miss the epic food disasters and creepy underwater things. Thiessen's delivery is great, and he's a superb editor. Combined with fab material, these videos are the perfect knowledge-snack for happy mutants.
