hi all..
i've been lurking for a while now, and i think it's time i added my 2

I was playing Fast Food the last night and i noticed that in between rounds,
the 'You're getting Fatter!' message scrolled from top to bottom quite
nicely, would it be worth your while disassembling that and taking a peek at
how they did it?
seeya..
