Radar PPI simulator w/RS232 data

develop a application to run on windows XP/Vista/Windows 7 which simulates a persistance (see jpg) 360 degrees sweep in about 10sec rotation. The swept picture should paint a stored landscape file to simulate a area. Each time it repeats the sweep a new trace is layed down (although the same picture/file). 360 degree sweeps or every 1degree will paint the picture. Your call on 1 degree swept arm data amount but it should be two color (black or green) with maybe 2 bit variation in brightness. Once this is done, RS232 comes into play.

RS232 will source of interference. See jpg. With low data numbers delimited by comma\'s (<20), nothing should be recognized. Over 20 (to 256) it should be OR\'d with stored painted data being swept on radial.

That\'s about it. I\'m hoping <$1k, as a crack programmer should be have problem with this.
