U - Topie Construction

The two figures on the right show clearly how “U-Topie’s” stair was created. On the left is a perfectly legitimate stair where the lower path passes beneath the upper path. By illegally connecting these two paths the illusion is obtained.

“U-Topie” is quite unashamedly based on this famous image by M. C. Escher and, unlike my “Cleaners”  image, uses a variation of the same the same Penrose Staircase construction shown on the right, although I have treated the steps differently and added a couple of twist and turns.
