This really blew me away when I saw it. It's an example of a simple use of Org Babel to translate phrases from English to Mandarin. Of course, all the heavy lifting is done by the Python library translate but the amazing thing is how simple it is to put everything together in just a few lines of an Org python source block.
Take a look and see if you aren't impressed. What I find most impressive is that it's just a quotidian use of Babel. It's merely that it does something besides add a column of numbers that makes it so spectacular.
