Waltron was a one-off gift for a departing colleague, and now it can be yours too!
It's a noisemaker machine consisting of two light-sensitive oscillators and an amplifier. One oscillator has a slower "beat" rhythm; the other is in a faster "pitch" range. Together, they combine to crudely mimic the cadence and intonation of speech. (Think: R2D2!)
