===== From sshaw@fas.harvard.edu: Are you sure that you want to reveal your secrets, showing us the other views of the box? Though there were several images with this optical illusion in them, I feel that you did one of the better jobs in making it easy to see it. ===== From trioker@wanadoo.fr: It's noticeable that three of us had the same idea of the "impossible" cube : Jack Kelly, John Hoerr and I (JMarc Genevey). Of course, nearly each and every of Escher's picures could fit perfectly the theme ! ===== From brendthess@aol.com: The second freemish crate... better done ===== From johnson@pharmacy.arizona.edu: Like it, my favoprite of the three esher entries this time. Well done showig how the illusion works, too! ===== From gmccarter@hotmail.com: The strong shadows from the single intense light source detract from the illusion. ===== From clem@dhol.com: The extra crates showing how the trick is done are a nice touch. ===== From sdevet@istar.ca: Nice! Lots of these things this round, though. ===== From bobfranke@halcyon.com: Interesting geometry. For improvement experiment more with the scale and rotation of the wood grain textures. ===== From file: Good pic, but everyone had to make the cube...
