Here is my first flash:)

I've got pleasure to do it and i shall improve it later.

Abstract allows you to choose brushes to draw or to create your own;
Use pallete to test brush;
Use "save u brush button" to remember current brush when you have changes parameters;
The "user" brush is to select the brush you saved;
"Eraser" brush is also changable, use it to draw simple lines or to correct the form of drawn samples.

Was some updated; "autorotation" feathure makes process easier and more current brushes can be saved :)
