Thanks for the explanation! It'll take some time to digest, but it works quite well :-)

Thanks! This is indeed quite fast. Would you care to explain how it works?

comment Problem with strings imported from PDFs
@ssch thanks, will do. For now I have found the temporary solution of finding and replacing all \.00 with a space and it works for now. It turns out that \.00 was the problem.

@ssch I use Import[location,"Plaintext"]

@ssch I get the same error so your expression stays unevaluated

@bills I went through the string and got: "V\.00" This still gives an error.

Try adjusting it manually by changing the values in BoxRatios->{1,2,3}

comment Changing the number of locators with SetterBar
@kguler Originally the button adds a locator at the position which is the average of all the other locators, but I removed it since it wasn't relevant to the question. So no, there isn't really a reason :-)

comment How to plot X and Y data to see average data converging?
I'm not sure it this is what you mean, but have you tried ListPlot[Mean[y[[;; #]]] & /@ Range[1000]]? It plots the average of the first n elements where n ranges from 1 to 1000. You can adjust the step size to give the average of the first 10, 20, 30 etc.. elements.

comment Defining regions for `Exclusions`
@Artes it's not that I don't mind the error messages, it's just that I'm using it in a presentation and don't want the graph to produce messages.

@Mr.Wizard Every second I want MyAnimation[time, dynamicVar] to evaluate and assign the result to dynamicVar.

comment How to create this four-dimensional cube animation?
@paradox2 I think he stereographically projected the vertices, but not the edges. I did something similar for the 600-cell some time ago and as you can see the edges are rounded, not straight. By using Line the animation can easily be confused with a perspective projection.
