Not beads, unless you count the micro ferrite beads (Hardeeharhar! Geek Joke)

I do stuff like this to focus on conference calls. Something mechanical and fairly basic like this helps me block out other input that would probably completely distract me from listening.

These are broken bits from various devices that I have collected, hacked apart, sanded, etc...and then wrapped. I think they look like some device found near an Aztec dwelling, something that would confound the diggers and bring about questions regarding their long-gone technological skill levels.
