Can you actually move the mouse cursor pixel perfect using this? I would assume different mice, mouse acceleration and/or sensitivity settings would result in the mouse cursor being not over the button.
I remember reading about someone having built an USB business card with some low-cost ATTiny chip that opens Windows Paint and draws some picture there. The author had solved the problem of mouse acceleration by faking a graphics tablet with stylus instead of a mouse.
