I always wondered if that was actually screen
burn in. As crazy as it
might sound I got the feeling that was actually a clear 'decal' of some
sort applied to the monitor. Don't ask me why on earth I should get such a
strange impression though.
Well, maybe they did run the 'fly-swat' Game for a long time ...
I don't recall the real name. You hat to 'catch' flies that apeared
around your window with a mouse klick ... they seamed to be random,
but they wheren't ... so if you just let this game run for a long
time, these flies will result in a visible burn in on your nice big
B&W screen.
