I saw the thread on using CR splines using keyframes, but these splines are easy to program for scenes where the geometry is well-known.
I made an experimental movie where the Eye moves around a closed-loop spline, and the Target is the combination of the tangent to the spline, and an offset in the y direction.
I made no attempt to visualize the spline itself.

would like to see your animation but problem with video? says can not play file is corrupt?

[JosLeys]

it plays allright here.
Make sure you have Quicktime installed.

got it, the grand tour of mandel island, nice.
the water looks inviting, how's the fishing?

Somewhere on my to-tinker-with list is passing a boatload of camera keyframe quats in a float texture to the shader and indeed have the shader interpolate. Might Make for a nice demo reel.

Would make it harder visualize that path though. Which really helps for those pesky spline over/under shoots on zooms.
