For Fidgeting

I have quite a few things on my desk just to fidget with while thinking.  None of them are purpose made, or even intentional.  They are just things that land on my desk and I don't get round to getting rid of.

A set of hard plastic corners from packaging
A broken BNC connector I cut off some coax to replace
Offcuts of antenna wire held together in a bulldog clip
A pipecleaner, currently in the shape of a musical note
A small wire tie
