I have to post the quickest blog about this ever - this on line lab is just amazing! I like the way it uses a Facebook interaction in a very clever way - try it out and see what I mean. It makes it personal and also gets across a very pertinent message.
If you haven't seen it yet, visit the ARUK Lab www.dementialab.org and then vote for it here in the awwwards!
This is an amazing bit of tech, but more important is the story it tells about dementia research.
