I remember as a kid having these plastic circles, maybe 5" in diameter. Had a pinhole in the center where you would tack it to a piece of paper. Had numbers on the outside edge. You would make a mark at the top of the wheel and line it up with number one. Then it had lines, arcs, shapes, etc, inside the wheel which were also numbered. You would fill in the one numbered 1, then turn the wheel to the 2, and fill that one in, etc. When you were done you'd lift up the wheel and have a picture of Mickey Mouse, Pluto, etc. I know my son would love something like that but I can't seem to find it and I don't even know what they were called. Any help or suggestions appreciated
