comment How do I represent a system dynamics feedback loop?
Maybe that's because I'm in a different time zone? No, the counter variable n in NestList simply starts at 1 while your clock starts at 0. It's just a numbering convention.

All you need to do is choose the rate and starting value to be the same as in your question, and use the function I posted. I've updated the answer.

comment Defining a non-commutative operator algebra in Mathematica
I would probably define a separate function like commutatorExpand and/or commutatorReduce that does the transformations in the direction you want.

@rcollyer Thanks for the alternative - it's documented under the Developer package, but it was new to me.

comment Importing base-64 encoded Canvas element into Mathematica
I can't make a blind guess. How are you exporting the JS code? Can you see the image in the browser if you call window.open(dataURL,'','left=0,top=10,width=500,height=600,toolbar=0,location=0‌​,resizable=0');?

comment Importing base-64 encoded Canvas element into Mathematica
I just had one additional thought: maybe it has to do with line breaks in your exported file. But since I don't have your exported file, I can't say more.

comment Importing base-64 encoded Canvas element into Mathematica
I've used this extensively, e.g., in this answer. So I see no reason why it shouldn't work for you. Something must be wrong on the JS side of your program, but that's beyond the scope of this list because you're generating the base-64 file incorrectly, but not in Mathematica.
