David Franco (37)

David was the first person from the slashdot discussion who actually came through with real element samples. It turns out he has all kinds of elements, some of which he sells on eBay. He initially sent a collection of 11 little vials of elements, but once he found out I could get him things with Mathematica logos on them, he sent a bunch more.
