# POV Ray
My ray tracing tool of choice. Plus Gimp to put the animation together.

# splendid!
hand coded animation then? impressive!

# Yep
I have a physics and mathematics background so you'll see stuff like

10+6*sin(sin(clock/10*pi)/5*pi)

a fair bit

# ahh
Does that give you a sin curve with steeper sides?
I'll assume that's the height of one of the robots bodies.

# No
The height of the robots is a simple sine. I don't think I used an equation quite like that in this one but that would be one where the angle of something operating on a circular path was a sin and then a displacement in the x/y direction was needed. I think I then used a cos of the displacement to generate a color value (the pattern in thing2 below) so three iterations in all.

I was going to make the blue robot's legs bow circularly but couldn't remember how to solve theta=a*sin(theta) so just made them a sine as well. Think I got away with it.

# nice!
yeah the legs look good as they are :)
