Look. I don't know how to do it either. But I'm on Athena, which is an
X-window system. So there are lots of programs running around here that
can use and display these bitmaps. Like, I've got a Bob-icon the size
of a postage stamp that activates a massive screen mutation program.
Without X, though, I got this little program that'll display a bitmap.
Got it in the mail awhile ago. You hablo C?
