Over at slash.dot, they trying to decode the real meaning of Intel's new VIIV logo for home-entertainment PCs. As a teenageer, I was fan of Chicago through to Chicago VII. Thus, my favorite explanation is by goombah99:
take all overlapping pairs of consecutive digits: VI II IV
that's 6 2 4 or in leet speak: "six to four"
Now if you assume the two (II) in the middle (VIIV) were crossed for multiplication (V X V) then that's 5x5 = 25
Hence we arrive at the Chicago song: Twenty Five or Six to Four
