I've actually gone down this path before, but I gave up when I asked this question: http://stackoverflow.com/questions/3644614/what-might-be-the-best-method-of-storing-mandelbrot-values-in-a-database http://stackoverflow.com/questions/3644614/what-might-be-the... Client input cannot reasonably well be verified, of course, but perhaps more importantly, once you get down to a certain zoom level, the advantages of caching the information almost disappears as the number of possible X, Y, and zoom levels starts increasing rapidly toward infinity. The other problem is that JavaScript has issues with very precise floating points and very high integers. Check out this Mandelbrot viewer that I made: http://janhartigan.com/creations/fractaljs http://janhartigan.com/creations/fractaljs (please be kind...my site is still under construction [where's my gif??]) It might take a little while to render, but if you keep zooming in (and upping the iteration value in the input box), you'll find that eventually things just start getting pixelated once JS reaches its maximum level of floating point precision.
