Remember the geometric statement necklace Lady Gaga rocked in her “Poker Face” video? Now it can be yours. Starting today, you can bid on the Brian Lichtenberg piece on Winnit.com—all proceeds will benefit The Lupus Foundation.  But there’s a catch: As always on Winnit, the prize doesn’t go to the person who places the highest bid; instead, you’ve got to try to guess the lowest dollar amount that no one else will pick. (A tip: $.01 is likely already taken, so you’ll have to get creative. We’re calling dibs on 83 cents.) You’ll have to kick in $1 to compete, but if you’re the winner, you may be able to own a piece of Gaga’s iconic style for only dollars more.
