An old Nintendo GameCube controller can make a fine desk caddy. Start by removing the mini joystick and use the space to store paperclips instead. Keep some of the buttons for aesthetic effect, but drill out others to hold pens and pencils. Retrofit the D-pad slot to become a USB port [source: Personal Money Network]. You'll have the coolest desk accessory on the cubicle block.
You can also find them already retrofitted and ready for your desk on Etsy.
