Low Tech - High Touch: Blackboard Web Cam?
I found a real backboard in the barn that my father used to use, but
sadly it had been broken in two. I must have something to draw on in
my office, and I always favored slate over white boards, so I laid the two
pieces on a sheet of plywood and expoxyed and clamped them, Then took some
leftover wood from the newly installed floor in the family room (heart
pine) and made a new frame.
What's nifty is that my blackboard is now featured in many of my
presentations - it's quicker to take a digital snapshot than draw it in
power point!
