A friend was a series of growing tubes to draw out a logo, using a series of splines and a Sweep Nurbs. He wanted to know how he could target the cameras focus to the 'tip' of the growth, as it formed.
I used driven keys and the Range Mapper Node.
Additionally, by tweaking the range mapper's spline cure, it is easy to delay/overshoot the relative position of the camera target.
(apologies for the crappy quality of the 'presentation')

Hmm…it looks like things are taking a while to load. Try again?
