ASCII Art? How about Unicode Art?
Youtube comments, generally speaking, are pretty convincing evidence that intelligence has not yet been conclusively proven to exist in the universe.
But every once in a while, something intriguing comes up, like this rather nifty example of Unicode art found in the comments under “Jack Cafferty Tells Us How He Really Feels About Sarah Palin” (apparently individual Youtube comments don’t have permalinks, sorry):
¨¤ø„¸¨°º¤ø„¸¸„ø¤º°¨¸„ø¤º°¨
¨°º¤ø„¸Obama & Biden„ø¤º°¨
¸„ø¤º°¨ ROCKS!!!``°º¤ø„¸
ø¤º°¨ ¸„ø¤º°¨¨°º¤ø„¸¨°º¤ø
If you’re curious, here are the names of the particular characters:
¨ DIAERESIS ° DEGREE SIGN º MASCULINE ORDINAL INDICATOR ¤ CURRENCY SIGN ø LATIN SMALL LETTER O WITH STROKE „ DOUBLE LOW-9 QUOTATION MARK ¸ CEDILLA
It seems to me that this little trick is just the tip of the iceberg; the possibilities for “drawing” given the number of characters in Unicode is truly terrifying impressive.

Hi Farzaneh,

Shift_JIS art. Also, wikipedia has an entire category for ASCII art. LiveJournal interests often contain unicode. My favourite unicode characters are the right-to-left control characters.
You have! I must have missed your that one.
