ILLUSIONY OPTI-WHAT-ICAL?

i have seen dozens and dozens of optical illusions. most of them are really cool. but so far i have to say that julian beever is the best at it. he does 3d perspective illustrations ... on the sidewalk with chalk. enjoy!

this next one shows just how big these are. julian is the guy on the bottle cap.

ok, this one has a side view as well.

this one just gets bigger and bigger.

here is another one with an alternate view.

i like this one a lot. the perspective is actually upside down.
