My wife and I love this kind of sidewalk art. Somewhere on one of the links our daughter sent us about a year ago, it showed how incredibly long the actual artwork extends over a section of sidewalk. That's why it is stated so clearly, that depending upon where one stands, one can see the optical illusion. Otherwise, it just looks like several sidewalk sections of scribbles with chalk.

Here's an example of "correct" and improper perspective renderings of the same chalk art.

This is so cool. Thanks for YOUR link above. We really enjoyed seeing this today. :)
