It is a long thread, but you'll probably find the final half is all about getting it to work/working around issues that never got sorted. I'd concentrate on mainly reading Art's posts. I can remember him mentioning the main issues somewhere, and I'm sure it was in that thread, although it could of just as easily been on the Mach yahoo group, as quite a few of his side projects overspilled on it aswell.

It's a shame he never developed LazyTurn more, but Gearotic Motion is his current project.
