10:26 pm - 35µs!
That's how long it takes my integer arithmetic based program to calculate the next point along a cubic spline on the Arduino. I am excited, aren't you?

What this means is I can can build animations with ease in and ease out to drive 16 RC servos independently (with a separate LED driver doing the PWM), and still have around 70% of the CPU cycles to play with. Or, put another way, this little chip could manage over 25k points a second driving a set of laser galvos without having to solve all the splines beforehand like ILDA files do.
