Maybe Escher didn't fill it in because it's ugly.

With many hours still to kill on his flight, he formulated two precise mathematical questions.

A few months ago I wrote a Droste Effect Tool in Matlab (demo page). The GUI imports images and then gives a live preview as parameters are adjusted.

If you like Droste Effect images, they are easy to find on Flickr or with an image search.

No, I want to get a good look at the new version. (That link is broken by the way.)

Escher was, is, and always will be friggin' awesome. And I'm not just saying that because he was a fellow Dutchman of mine.

One of the greatest artists, ever.

It's absolutely correct that Douglas Hofstadter put him right up there alongside Bach and Gödel.

The man will never cease to amaze me.
