The Easy Cloud contains 3 built-in fractals (at the moment). All of the built-in fractals are limited to 256 seeds each (because they suffer from the same limitation as the Power Fractal). However, I added some extra randomness by calculating a random seed for just one of the built-in fractals based on the 32-bit input seed. This makes it harder to find duplicates, but they still occur quite often. Theoretically there are now 65536 combinations, but the duplicates will exist in somewhat random places, so you'd need to try a much larger set of seeds if you wanted to find them all.
