AS3 Sound Spectrum Experiment

I have recently created an actual site for myself for the first time in years in order to host any experiments i do, and here is the first one. An experiment using the compute spectrum function to create useless but pretty graphics using the lovely bitmap filters! (click in the top half of the flash to switch between the two modes)

The source code is there to download. If anyone has any comments or crits on the code i would love to hear them. Hopefully there will be more experiments to come. I have a couple lined up but doing html bores the hell out of me so it may take me some time to actually get them online!

Let me know what you think.
