TL;DR A stylish necktie with magical musical powers
The most sylish volume control you can wear! The always there, invisible hardware that worn in your zoom meetings can control your microphone and volume level and un/mute with a tap on the knot!
Pop in a MIDI instrument, or connect over bluetooth or USB and now you've got a polyphonic musical instrument, like a soft keyboard but with pressure sensitivity and aftertouch.
Finally, a reason to attend meetings!
