Author's Note: M. C. Escher's home.
There are at least 27 errors or oddnesses here, from odd lighting to distorted/impossible perspective. How many can you find ?
You might recognize the buglike critter at bottom right, from some of Escher's work. I drew him from memory.
Usually I can't tell the difference between compressed entries and full-size-- but this time, the compressed version is only about half as visually effective as the full-sized version. Take a peek at the full-size, won't you ?
