Aardman Digital has released several very good Flash games in recent months. Home Sheep Home is great fun, but isn't really all that relevant to educational games so I'm not going to spend any time talking about it.

Their most recent game Sprocket Rocket, was created to teach about the various functions of the the UK Patent and Trademark office. The game features the eccentric inventor Wallace, and his patient assistant Gromit, from Aardman's famous and award-winning animated Wallace & Gromit films Players get a crash-course in intellectual property law by flying their little steam-powered rocket pod around a map and collecting little stickers that reveal small snippets of information about copyright, trademarks and patents. The way the game delivers the educational content isn't that impressive, but the way the game gets players to care about that content definitely is!
