What do you mean by Spherical Geometry? Spherical Coordinates?

Right, an elastic membrane, but couldn't you do something with a bucket? :P

@Michael I don't think $f$ should be in denominator like that, since it just automatically cancels each time. See my answer below

@Michael so you're saying $n = $ points per cycle. Okay, then t = k / pointsPerCycle in my code above?

@Michael not sure what you mean. Please make an answer and see my above edit with code. Sorry for my boneheadedness at the moment!

They are exactly those elements (minus the 5 in your example).

@AndréNicolas by automatically even do you mean $2f(X)$?
