Okey-dokey: "L.H.O.O.Q.", as the Wikipedia entry goes, is a "work of art" (quotes are mine) by Marcel Duchamp, who took a Mona Lisa postcard and drew a goatee on it. Voila--instant art! I figured blatant, unapologetic copying made sense in our little rep world, and "Lichtenstein" was too long and too on-the-nose.
I was ready to use a crop of the actual LHOOQ as my avatar, but decided I didn't want people to imagine me as a bearded lady. (Not my scene, man.) Instead, I went with the face of Paul Freeman as the similarly-lettered Rene Belloq, evil French archeologist, and arch-nemesis of Indiana Jones.
"Look at this. It's worthless - ten dollars from a vendor in the street. But I take it, I bury it in the sand for a thousand years, it becomes priceless. Like the Ark."
Also, like WM9s!
