I’m having a hard time understanding what this one even is. (Because I’m a sane person, and things like this can’t be understood by the sane.)
I think this means that it’s a robot that has a microphone shaped like a human ear, and if you point it at something that makes noise, the robot moths in the robot’s clear head will start to spin around in a circle.
This seems like exactly the sort of useful invention I need.
Of course, if funded, the original goes to an art gallery. (What kind of gallery displays moth-headed robots with human ears?)
But if you need one for your kitchen, a $40 pledge would have gotten you the plans, and the ear.
