FFTPaint revisited

In my original project I was doing pretty much what FFT is supposed to do except it was doing it in color. That is not significantly different from the gray scale, but looks cooler.
The interface was kinda clunky - heu what do you want from my first Java applet :-).

So, I made a few changes to the interface:

get rif of the checkboxes on top to make it look less busy (well, the sad part is that maybe the functionality is important, but in this case I found I never use some of it.
Replace the radio-button-style palette with something more pleasing.
Dynamically select the brush size, depending on the speed. I think I like the slightly counterintuitive feel. The logic is that when you are moving slowly, you probably want finer control. So, the brush gets smaller.
Speed it up

So, drag the mouse over the top part of the palette and select the color. The white rectangle on the bottom shows the current color and luminance. You can click there to change brightness.
