Make Nifty Christmas Ornaments
Why not use those old, scratched-up CDs and DVDs to create unique ornaments for your tree this holiday season? As shown above, almost anything could work--motherboards, graphics cards, old modems, or hard drive platters--you name it. The disc-based versions would probably be a better choice, reflecting the strands of lights draped nearby. Heck, for an even geekier tree, you could paint unused Ethernet cables to replace the garland. Old CPUs and fans, sporting festive colors, could serve as unique makeshift decorations, too.
