comment Switching among view points in a Manipulate expression
@Kuba that zoom effect always happens when you drop out of an Infinity perspective, it's not related to the Dynamic. the lack of zoom does make rotating meaningless for that perspective though. i'm not quite sure how the whole thing would be properly fixed without adding more variables and stuff. @DavidCarraher, yea, the version with Dynamic is faster because the Manipulate doesn't re-evaluate its body, so the Pause isn't run.

comment The guidelines for options or multiple arguments?
A mechanism that I use sometimes, which isn't obvious, is to make the function all option-based: f[OptionsPattern[{a->1, b->2}] and then specify certain succinct forms: f[x_Real, rest___] := f[a->x, rest]. it's very convenient

comment On reimplementing the Select function
@mr.Wizard aye, that form is what i would use in my own little codes, it's not meant for performant robustitude. your function is almost exactly what i was going to post before the thread was closed, except with pattern matching on the output of Reap like this: {{_, {}} -> {}, {_, {out_}} :> out} to handle the case where the length is 0. then again, that could just be checked in the beginning. derp derp.
