One Object Three Shapes: The Solution
In an earlier post, One Object Three Shapes, we posed the problem of finding an object that would appear to be a triangle when viewed in one way, a square when viewed in another way, and a circle when viewed in yet a third way. The challenge was to create an object that would fit through and completely fill each of three openings cut in a sheet of paper.

You will recall that Erin and I talked about the idea of looking at objects from top and bottom, left and right, and front and back. We were looking for an object that would appear to be a square from the top and bottom, a triangle from the left and right, and a circle from the front and back. This was a new problem for Erin, and she promised to work on it herself. In the video, Erin I and get back together to talk about her solution to the problem.

Great puzzle and a great video. You two work really well together on camera. This one was a real stumper for me, but the solution seems obvious once you see it.
