This is a group for images showing the same type of transformation used in M. C. Escher's "Print Gallery" (Prentententoonstelling).

The transformation (complex exponential) is described here and here.

We're discussing how to tag your images. Check the forum! Please tag your images with "droste:p1=XX" and "droste:p2=YY" where p1 and p2 are the parameters of the image (usually 1,1 or 1,-1, it depends if the spiral grows clockwise or counterclockwise respectively) described by gadl. Don't forget the quotes!
