Cuisenaire Cat

If you know Gerro at all, you'll know he's crazy about wild cats.
And craziest of all about cheetahs.
Lean and keen, I think he sees himself in them.
Well, the other day he was very busy with his Cuisenaire rods (see http://en.wikipedia.org/wiki/cuisenaire.)
Assumed he was working on some simple arithmetic.
But upon investigation ...
He'd conjured up yet another cat.
A cheetah.  Of course.
Flying along at full throttle.
What else?
