Very nice! I've never heard of it being done for charity.
My buddies in University used to do "Neanderthal November", and not shave for the whole month. Or "Exam beards" and not shave from when they started studying until the end of exams.
My project group right now consists of myself and two guys. They suggested doing "Don't shave until the project is done", but it was vetoed it after all the jokes they made about how I could contribute to it....
