Everybody loves a good optical illusion - and this newly discovered perception trick has us questioning how we see the world around us.

Take a look at those lines in the image above (or you can see the full picture below if you scroll down a bit). What kind of lines do you see? Are they straight, edgy zigzags, or soft, curvy waves? Do you see just one kind, or both?

All these lines geometrically exactly same curvy waves. The only difference is color pattern. On some pattern highlights curves, on the others more straight inter-curve connections are highlighted making it look like edgy zigzags.
