Screwed Up (2006)
The image was created for contest of Escher like 3D artworks "Optische Illusie ala Escher", which took place at forum http://gathering.tweakers.net/forum. There's three classic impossible figures here: impossible cubes on the table in the front, crazy crate on the pedestal, impossible triangle on background. Moreover, the shape of the room is impossible. Three reproductions of famous lithographs by M.C. Escher are placed on the walls - "Ascending and Descending", "Belvedere" and "High and low".
Wooden crazy crate.
