I was hoping for something a little more OK Go than this... Pity there's no real substance to the article, it would be interesting to see how speed alters the tune, I'm assuming that changing speed doesn't have a linear relationship, otherwise as said elsewhere, 90mph would mean an octave up and twice the tempo.

Multiply the speed by the 12th root of 2 (1.059...) to transpose up a semitone. Repeat for further semitones.

When you get to the 12/12 root of 2 you get a factor of 2, which gives you 12 semitones up at double the speed.

I have a strong suspicion that is exactly what would happen.
