software similar to sidetrack for trackpad

So I had something installed previously on my powerbook g4 1.5 15inch that made it so the trackpad had scrolling capabilities by using two fingers. I just did a clean install to upgrade to Tiger and thus don't have that program anymore.

I did a search but only came up with sidetrack which I don't like.

Anybody know of the other one that I may have had?

Thanks

Thats iScroll
