i wonder what method you use for creating tile images, my method was always to copy 4 parts of left/top/bottom/right together to create a tile, this works nicely for images that look somehow layered afterwards, but you are creating nice sharp single images, this is nicey!

perhaps you could shed some light to a dream i have:

i would like to have multi-tiles, i mean to create a number of tiles that fit perfectly together, in any order ....

which is needed for texturing realtime large planes, i mean i read some paper some day where it was stated that 4 tiles are enough to create an endles surface with non repeating ( human recognizable ) patterns ... any ideas for that ?!

i have some ideas, but i am not satisfied with it....

Actually I'm not doing anything!!! The image is the raw Julia. The tiling nature of the image is probably the result of the fact that the equation happens to generate an orbit for companion points on either side of the image boundary (-2 to 2 in x and y) with the same magnitudes along the orbit and the Exponential Smoothing based coloring returns the same value for these companion points. Sorry I can't help you with your dream but this happened by accident, although I guess you could engineer your fractal equation with respect to your coloring algorithm so that the companion points produce the same value. That won't help you with generating a tile from an arbitrary image of course.
