Just because it's Monday and you obviously need a break, let me present to you the greatest mind f**k of the century, or at least of today--Monday, July 6th.
Take a look at the below (not for too long--I tried that and will now likely vomit) and notice the green and the blue spirals...
Now ooh and aah when I tell you that those spirals are actually the same flipping color. The orange spirals do not in fact go through the 'blue' spirals as they first appear to and the 'blue' is contrasted with a magenta, playing all sorts of wild tricks on our eyes.
Don't believe me? Well, I didn't believe in Santa Claus and then a reindeer landed in my backyard one day, so there you go.
