What is this hidden sticky directory doing on my Desktop?

http://superuser.com – On my Mac I just encountered a hidden directory on my desktop. I don't recall putting it there. When I type ls -la in Terminal on the desktop I get the following: The last folder is what triggered my attention. It is also highlighted meaning that this is a sticky folder (not sure what that means). When I cd into that directory and type ls -la I see: total 16 drwxrwxrwx@ 4 user staff 136 Oct 18 2012 . drwx---rwx 17 user staff 578 Dec 17 15:03 .. -rw-rw-rw-@ 1 user staff 231 Jan 16 2013 6VR16NQEUJ456542VDR66LS7 -rw-rw-rw-@ 1 user staff 226 May 8 2013 K7wuT15oKsg= The 6VR.
