An entry in the ShortestWikiContest. WyRiki is 20 lines of unreadable Ruby code. The design was shamelessly stolen from the WyPy entry. 

You can see the code here: http://onestepback.org/misc/wyriki.txt.

There is a live version at http://onestepback.org/cgi-bin/wyriki.

The author confesses to writing it late at night when his better judgment was impaired.  Plus, leaving off the final "i" in WyRiki gives a phonetic spelling of the author's name (which is the real reason he wrote it).
