Definately AMIGA
rrrrrrr Just that sweet memory when the cool guys had such a machine, a machine with back then to me mysterious and unlimited possibilities game-wise...
Checker flag is O.K. but small, not as outstanding as the AMIGA logo. And a combination isn't a good idea either, too much is too much of nothing.
Oh and yes, I kinda agree with the thread starter, the boing ball is boring as hell.
(yet I wouldn't mind having an Amiga 1000 with that logo)
