DIYbio

Not quite sure what these guys are doing, but it does look interesting:

DIYbio is an organization that aims to help make biology a worthwhile pursuit for citizen scientists, amateur biologists, and DIY biological engineers who value openness and safety. This will require mechanisms for amateurs to increase their knowledge and skills, access to a community of experts, the development of a code of ethics, responsible oversight, and leadership on issues that are unique to doing biology outside of traditional professional settings.

There's a lot more info at their Wiki. They're based in Cambridge, MA, but have local cells (so to speak) around the world. Check them out!
