Gene Levine recently emailed a couple of new 3D stereograms that he has been working on.  Below is one of these images which he calls Cat House.  If you stare at this pattern, a hidden image will reveal itself.  Can you figure out what it is?

In 1961, famous Dutch artist M.C. Escher printed a lithograph titled Waterfall.  This print shows a seemingly impossible scene with water flowing uphill to create a perpetual waterfall using the same water over and over again.  There is a paddle wheel at the bottom of the waterfall which we would assume is what powers the water back up the hill.  Many artists have created derivative works or art inspired by this very intriguing concept.

Here, Italian artist Alessandro Diddi has sketched a three-dimensional anamorphic version of the waterfall that appears to literally stand off the page.  In reality, it is all drawn on a perfectly flat sheet of paper.  He has cut some sections of the paper away to help add to this optical illusion.

A man with a lantern emerges from a grouping of pine trees and approaches the edge of a lake.  As he looks down the coastline, the pine trees transform into skyscrapers in the night.  Can you tell where the pine trees end and the skyscrapers begin?  You have to wonder when Rob Gonsalves painted this if he is making any commentary about the conflict between nature and development.

The University of Arkansas at Pine Bluff is a university located in Pine Bluff, Arkansas.  The school was founded in 1873 and is the second oldest public institution in the state of Arkansas.  It has an enrollment of over 2,500 undergraduates and 100 graduates.  The school’s mascot is the Golden Lion and their logo is quite intimidating and vibrant.

Do you notice anything interesting hidden within this logo?

Check out the wire sculpture in the video below.  From one angle, it appears to be a pair of giraffes standing next to one another.  As you walk around to view the sculpture from another angle, however, it transforms into a completely different animal – an elephant!  I would imagine that it is difficult enough to make a wire sculpture of one animal.  The thought of making one that would present two different animals from two different angles in completely mind-boggling.

This very unique sculpture is similar to the squaring the circle optical illusion.  If you haven’t seen that one yet, you should certainly check it out.

Professional painter Stefan Pabst shows how to to draw a 3D ladybug in the following video.  The video is sped up, so you won’t exactly get step-by-step directions to create one for yourself.  Nevertheless, it is pretty amazing to watch this anamorphic insect come to life on paper.

Is this clown on the tightrope walking upside down or right-side-up?  Without the placement of the moon, you might just assume that the black space in between the buildings is the ground.  But since the moon is there, it almost feels as though you are on the ground looking up toward the tops of the buildings (therefore making the black space the sky).
