my mouse callous, of course -- what the hell else would i be referring to? (people need to get their minds out of the gutter) are you a computer slug? do you bear this telltale brand - the notorious mouse callous? if sherlock holmes were around in these times, he wouldnt have to try very hard to identify the hardcore computer slugs among us :) the mark of the computer slug - the unholy offspring of hundreds of hours of dragging the mouse hand across a computer desk or mousepad... so come on folks, get your digital cameras out and snap a pic of your mouse callous - display it with pride, and share it with the world. but i bet mines bigger than yours :) ive been developing it for over 6 years now. if i actually saw the light of day and had any more skin pigment it would show up much more clearly :( cheers, -gabriel
