Amazing Anamorphic Illusions!

“These illusions were created by an artist who calls himself Brusspup.What he does is an exercise in anamorphosis, a conjuring trick that takes advantage of how our brains make sense of the world. If you know how, you can create an image which makes no sense until the viewer happens onto a particular — and it’s a very particular — spot. Once the viewer finds the right angle — the only place where he or she can see what the artist intended — suddenly, boom!- the drawing leaps into three dimensions.”
