Working with Hydra for some days gave me a better knowledge of how things actually work and I thought it might be worth trying something that is a little bit harder. It is very funny to implement a complex filter on the one hand and keeping it Flash compatible on the other hand. You will see a lot of this in the code.
I really enjoyed writing this one. It helped me again a lot and I think you might learn a lot from the source code as well. By the way I started first with a k of 4 but that was crashing Hydra all the time. Might have looked better but 2 is also ok. Have fun!
