do a google for kaos-rhei. the derived images can be converted into a terrain or lattice or as a 2d image. you can also derive kaliedoscope like patterns by using various transparent primatives alone or in combination with your lense close to or inside the primatives. There's a lot more to it of course.For example, Vile made a telescope using the refractive properties in Bryce - You might want to check that out although his telescope wasn't fractal, the idea of refraction is interesting. There is also the chance that you could do something in the deep texture editor if you can find the formulas. do a google for mandelbroot sets or julia sets to see if you can find these formulas. (I havent tried this but it might work.)
