I’ve been helping the UK’s National Physical Laboratory (NPL) with their NanoLands project in Second Life. It’s all about nanoscience and nanotechnology. They’ve just announced a new program called The NanoLands Challenge: if you can think of a cool exhibit about nanoscience or nanotechnology, then let NPL know and they might award you $400 or $700 USD to get it built.
