Semi-random but kinda cool; check the full post
As many of you know, Twitter limits you to only 140 characters in each "tweet." That doesn't sound like much... but if you try you can cram a good deal of data in those 140 characters! In fact, Quasimondo figured out how to tweet a pretty good version of the Mona Lisa!
The technique was pretty clever: Tweet in Chinese! Twitter allows you to use UTF8 characters, which means if you pick a language with a lot of possible letters -- like Chinese -- you can encode a great deal of data into one single letter. If properly encoded, you can cram 210 bytes of data into 140 Chinese letters.
