The mapping algorithm becomes quite simple once you realize that there are only four possible path segments — their shapes resemble the letters A, C, D and U — and that they decompose into each other. The U segment, for example, becomes D-U-U-C. The image on the right shows the path from 0.X.X.X to 255.X.X.X.
-Each tile has a size of 256 by 256 pixels, and its file name is the range of IP addresses it depicts. For example, at the highest zoom level, the the top left corner tile is "0/0.0.0.0-0.0.255.255.png". This naming scheme is pretty, but combined with the fractal projection, it makes translating screen coordinates to tile names somewhat more difficult than in most other map applications.

Another challenge is the fact that nation states, since they were invented long before the Internet, are represented by flags and not by icons. These flags tend to have weird aspect ratios and don't work well on a map that is essentially a square of squares. One could just crop or resize them, but in most cases, the results look surprisingly stupid.
