Any success with approximating/interpolating that with a linear function?

Personally, I'm just short on time, with way too many similar projects.
That and the fact that I can't just hack on it for a few minutes when
I feel like it because the battery is somehow always drained and the
stupid thing doesn't run on USB power without it are the cause for my
current silence.
Whether or not the hammerhead will be in GTA02 does not matter to me at all.

cheers
