In the US in the 90’s there was a pen, IIRC it was marketed as the Squiggle Writer, which was basically that. Fairly large plastic pen that had a vibrator at the far end, and interchangeable ballpoints that could be slotted into the writing end. When running, as you wrote with it it would cause the pen to draw little loops.

It was a plausibly deniable sex toy.
