This is a neat little add-on i found that lets you make realy cool pictures in WoW chat, like hearts, music symbols, etc.
The first time i did this i got spammed with "ZOMG HOW DID U DO THAT?!?"
So it should provide you with some fun in trade chat.

After a while i also came up with the idea to start selling how you make these, i made a bunch of plain letters that told you where to download this add on and how to install it, and put them on AH for 5g each and starting advertising it, within 2 days i made 160g, then they kinda stoped selling, hehe kinda evil, but a good idea to try in your spare time =D

Anyways, here the direct download link: http://rapidshare.com/files/141343158/LessThanThree.zip
