I completely forgot about that. Just for future reference--

http://code.google.com/p/pygep/wiki/SymbolicRegressionTutorial

Usually formulas from symbolic regression are really, really terrible,
although that's vanilla without anything fixing the terrible
equations. Also, gnuplot has something that is more akin to curve
fitting and is not symbolic regression.

I would be excited to see a sympy symbolic regression library tied up
to a genetic algorithm (or some other search algorithm).
