Here are a few of things I'm looking to do:

Calculate velocity/acceleration from a stream of numbers: I have a camera that outputs x y & z coordinates of a tracked object. How could I figure out how fast it's currently moving?

I'd also like to do some kind of model based sonification where I hear how fast an imaginary disc is spinning: So I apply some rotational force on that disc for a certain amount of time, which speeds up how fast it spins (represented by pitch or amp mod or something), but then it slowly goes back down to 0 rpm due to friction. I don't need to "see" the object using Gem, but just calculate how fast this thing would be spinning given some force applied.

Any help appreciated. Thanks!

If I wanted a less fine grain measure (rolling velocity over the last second if I'm getting a position reading 60x/second, could I just zl group 60 and take the mean of that list every second?
