Dean was a super-enthusiastic tinkerer. He'd often grab me as I came in the door to show me what he'd come up with over the weekend. I hosted a website and a mailing list for him at one point, but he changed things around so often that I never really knew what was happening :-)
Dean was blind, and was an excellent example of how blindness doesn't have to stop you from leading a full life, getting a job, etc.
Bye Dean :(
