The plug-ins aren't even my best invention. My best invention is this:
You take an old woolen glove, preferably one without a pair, and cut off the thumb, index and middle fingers. This way when you work on a pen tablet your sweaty hands won't get stuck on the tablet. And it's a lot cheaper than the smudgeguards
sold on the wacom site.
this is what airbrush (the real kind) artists would do when painting on animation cels.
we would take thin cotton gloves made for this purpose and cut off the tip of the trigger finger and maybe the thumb. And this would prevent us from getting sweat and finger prints off the plastic.
what is old is new again
