Close, but not quite; there are 16*16 (=256) bits in the mask, as well
as 16*16 bits in the icon, for a grand total of 16*16+16*16 (=512) bits
total, or
	2^512 which I'm not even going to think about calculating,
	except to point out that it's roughly 10^153.

And, of course, on MacII's and EGA PC's, there's color!
