That's right, the UK branch of the Mensa society for smarty pants has released a brain training alarm clock that combines groggyness, loud noses and puzzles (a winning combination). Here's how it works: when the alarm sounds, you will need to memorize and repeat a random sequence of colored lights on one of three difficulty levels. If you get the sequence wrong, or you are too slow, the alarm gets progressively louder until you get it right (or hurl it against a wall). If you are up to the challenge, the clock can be yours for about $41 shipped to the US. [eBay via Craziest Gadgets]
