...That's "binary pencil holder" for people who actually have a life!
I made this as a birthday present for a friend of mine who's an engineer. It's a pencil holder made from old 3 1/2" floppy disks. I used the two holes on the bottom edge, then drilled two more at the top and connected them together as five sides of a cube with cable ties and superglued the metal slide-y bits so they didn't bend off (seriously. You can make or mend anything with the right combination of cable ties, superglue and duct tape.) I'd already made a non-binary (and not as awesome) pencil holder for myself.
...But where's the binary?
This was a challenge. I converted my friend's name, William, to binary using an online binary encoder (http://www.theproblemsite.com/codes/binary.asp
) and cross-stitched it in wool on some massive aida I had lying around. The black stitched are 0s and the white ones are 1s. That was pretty easy, once I'd planned out the chart on some squared paper. What was hard was dismantling the floppy disk without damaging the plastic casing. I ended up using a combination of brute force and really sharp scalpels to cut through the plastic rod bits that hold the disk together. I cut out the portion of the disk where the label normally goes (that was a challenge!), then interfaced the embroidery and sandwiched it between the two halves of the floppy, replacing the metal circle from the back side of it. The cable ties kepts the two halves of the disk together (helped by a generous amount of superglue, of course)/

And the whole thing! Helpfully modelled by my laptop.
I apologise for the poor photo quality... :s
Thanks for looking!
