Using the Point on Curve Info node

I always think this kind of stuff is pretty cool. . . a) this node is semi-secret/hidden and you'll feel pretty cool showing it to someone who's not aware of it (though don't be too smug. No one likes that asshole) b) you get to create some stuff using the command line, which again is pretty sweet and nerdy and c) the pointOnCurveInfo node is exactly the kind of node that riggers like. It just does what it's sposed to do with no extra fussing around or additional junk.
Anyways here's a video talking about how to access this node and some basic ways to use it (namely for sticking stuff onto a user-defined point on a curve).
A quick tip, which is in the video and which is a reiteration of info I've posted before. . .
Rather than using:
createNode pointOnCurveInfo -n "name";
which will give you node, but leave it hidden from view in the hypershade, I prefer:
shadingNode -asUtility pointOnCurveInfo -n "name";
which does basically the same thing, but flags the node as a "utility" and thus puts it under the Utility tab in the hypershade. Just thought I'd point that out again.
