This site allows you to turn any image into a fractal or hyperbolic tiling (see image). The program is probably a little rudimentary compared to some of the fractal programs out there, but it’s easy to use and web-browser based. Firefox may be required for some features.

The site also has several more conventional fractal creators, but I recommend a more robust program if you’re looking for more features.
