This optical illusion is so simple, yet so deceptive, that you should try it on your friends, and use it to win some bar bets, too [flash: 1:20]
Now on ScienceBlogs: "Investigative science journalism" and books I like to read [All of My Faults Are Stress Related]
"The universe is full of magical things, patiently waiting for our wits to grow sharper." -- Eden Phillpotts.
GrrlScientist is an evolutionary biologist, ornithologist, aviculturist, birder and freelance science and nature writer. A native of the Pacific Northwest, she relocated from Seattle to NYC with her parrots after earning a BS in Microbiology (emphasis in Virology) and PhD in Zoology (Ornithology) from the University of Washington. In NYC, she was the Chapman Postdoctoral Fellow at the American Museum of Natural History for two years, pursuing part of her "dream" research project by reconstructing a molecular phylogeny of the parrots of the South Pacific islands. GrrlScientist has written a blog about science since 4 August 2004 (the early years are archived here) and was part of the original invited group of 14 "SciBlings" -- her only claim to fame. If you appreciate GrrlScientist's writing, please help her pay her living expenses by clicking on the Paypal button below and by voting for her to be the official blogger on a month long adventure in Antarctica. If you read an essay that you especially enjoyed, please nominate it for OpenLab2009.

Very cool. Elegant as well, stripped to its bare essentials.

I think it's probably because the legs are bent out. the legs are farther apart at the bottom on the left lengthwise.
Cool though

Grrl, you might add a note that this illusion (and those very drawings, in fact) was created by Roger Shepard. This illusion's been floating around the internet without attribution for too long.
