Perfect Square

by George Barany and Friends

This insanely difficult puzzle (6x6), with no black squares, was constructed in honor of a certain special individual on a certain special occasion. The artwork pictured to the right was not chosen at random.  A much easier puzzle, found here, gets to the same overall result. After completing one or both puzzles (spoiler), or in case you just throw up your hands in despair, click here for the solutions and explanations.
