I have two versions of Macromedia Flash (MX 2004 and 8) but I never used it before... this is just me screwing around in flash. It is somewhat easy, but aggrivating to get the lines just right.
Oh yeah, done with notebook touchpad mouse (minimal usage of Wacom tablet).
Another thing... It'll probably worry people when they see the small view because it appears to be a black square. It's not; transparency appears as black in the small view. Full view this to see properly, please.
