The ultimate in nerdy Christmas trees: a small tree made from old, obsolete memory modules. Everyone who ever built or upgraded a computer has some of these laying around, and as they get old and too low-capacity to be of any use, they lose all purpose. But it's hard to throw something out that still works, isn't it?
Since they are mostly green, and have nice shiny copper strips or pins, they're perfect for a Christmas tree. And don't we all want a Christmas that's made of good memories? There you go! *badum-tishhh*
