This is really cool. I am always in Org mode which lets you do "literate" programming as well. I think NoteCalc is a little more streamlined, but I am very used to throwing a little Python or elisp into my notes when I need to do math. Great to see more options on this front. Org-babel is a nice package, though it does have some limitations.

Any reason you don't use calc-mode to insert mathematical results into your Org buffer? Calc-mode is extremely powerful.
