shadebob noun1 •A type of bob (graphical sprite-like element) rendered additively on the display, so that it blends with others but can be easily removed again by decrementing the colour value at each pixel.If I made a shadebob routine, which ran 60Hz on PentiumIII 550Mhz on 320x200x8bit mode, would you be impressed? — 1999 formsshadebobs
