Introduction

What should a robot with 3-D manipulative capabilities (including a TV camera, and an arm with gripper) do if it is

shown a pile of rectangular blocks on a table
shown the pictures below, and
given the command
"Please use the blocks to make what you see in the picture"

NOTE
The line drawings are based on a picture produced by the Swedish artist Oscar Reutersvärd in 1934, as reported in http://www.sandlotscience.com/EyeonIllusions/Reutersvard.htm

A penrose triangle made from folded paper

The following pictures represent my not very polished attempt to use the template available
at this excellent web site http://www.coolopticalillusions.com/build-an-impossible-triangle.htm

You can see a movie there.
