Sounds very similar to my approach in several aspects.

Things that may differ:

Your method takes an offset into the spline - with my macro this is a
property of the spline, i.e. for a given time value a given point is

Your method takes a step length - with mine the step length is variable, and
gets longer at higher speeds. Of course you can specify the time/length
relation, but it will always adjust to the speed of the spline. How does
your method work with regard to variable speed walking?

That's funny, I've been planning to do exactly the same!

Well, I'm aiming for a general solution that can be used for practically any
walking thing, from humans to animals to weird robots...

I'd be interested in hearing more details about your approach! :)
