Wait, so is this optical illusion straight or curved?

Who doesn't love a good optical illusion? Whether you're into rotating horses or topsy-turvy celebrities (both of which we've seen recently), there's something for everyone in the wacky and wonderful world of mind-benders.

At first glance, it looks as though this example features many rows of curved and angular lines, but the closer you look, you soon realise that each line's curviness is dependent on what colour background it's on.
