Why bother with photoshop when you know how to photograph optical illusions? That's the theory of Li Wei, a Chinese illusionist photographer who used to be a painter. He takes rad photos, doesn't touch them up, and marvels us all.

Unfortunately, Li Wei's performance art site appears to be down, but hopefully the link will be back up soon...

Implications - Illusions bring the joy of seeing something fantastical to viewers who often need to see something fresh outside of their daily lives. Certain images are obviously Photoshopped, but when it's hard to tell, companies can lure in consumers by arousing their curiosity in what's being sold; it would also make a great viral marketing strategy.
