OK, you're right, but I still content that it'll look pathetically bad. First,
the uTV (MicroTV, I'm *NOT* typing it out anymore) screen is only 128 plxels
wide (or thereabouts). So it's in about a 1:6 ratio with the the size of the
screen. Compress the screen by a factor of 6. Now compress it by a factor of
6 again (recursion, eh?). It doesn't take too lokg to get an image that is
too small to be seen. So you're really not going to be able to see all this
wonderful recursion... it will only change if you move the uTV window, and
then it will visibly stabilize by the third level of recursion, which
should take considerably less than a second, even with a uTV and Flicker-
Filter slowed down machine.

Fair enough? I tried not to make any pompous statements this time...
