Grant Rettke over at Wisdom and Wonder points to an interesting project that integrates Org Babel and Applescript. If you’re a Mac user and sometimes work with Applescript (or even if you want to play around with it) you should check out ob-applescript.org.
I don’t really know Applescript but I have figured out enough to allow me to grab links to the URL for the current page in Safari. If you want to play around with Applescript or try implementing little helper functions, this is a nice way to do it while taking notes on your progress.
