Project for Awesome has done a very neat link with YouTube, using a little logo attached to the YouTube logo (top left).
Have a look at what they’re doing on their YouTube channel and at their site (the quick precis being “mass charity awareness/action using YouTube videos”). Comments gain corporate donations, links help build it. It’s charity done viral. Awesome stuff.
Incidentally, Megan Fox is not a part of this (to my knowledge). Her appearing in the main snapshot above is pure fluke, however awesome you might think she is!
