THIS overhead projector. Why? Because they are pretty much one of the best inventions on earth. I cannot tell you how many times I have taken a picture that I wanted to make larger, copied it onto an OHP sheet and projected it onto my wall/canvas/sheet and recreated it as a much larger image. It is one of the best tools I have used to recreate everything from Bethlehem to Goliath. I am soooooo tempted to just buy it. Should I?
