I’ve become a frequent reader of the Proceedings of the Athanasius Kircher Society website, and today they had a neat link to some examples and descriptions of an optical illusion called the “Droste Effect”.  You can find alot of beautiful examples of it in this gallery.

In short, the effect gets it’s name from the old Droste Cocoa package which had a picture of a Nun holding a box of their product on a tray, and on the box was the same picture of the num with the tray, creating an infinite recursion.  It’s a pretty well known effect, but still amazing.  One thing, tho, I had never seen before was this incredible article on a Mathematical Implementation of an Image Warping routine to generate these effects.  They have plenty of examples of them taking ordinary images and creating some really stunning effects using this “logarithmic image transformation” algorithm. 

This would be a fun project to put together in Matlab, or even ITK.  A sweet Photoshop plugin would also be neat.
