This is amazing!!! I'm inspired to experiment more with paper-based 3D structures like this!
Spinning Paper Cube Globe
Bo Peep's Skunk Mobile - Remote Control Plushy

Wow, Meccano looks awesome! It's my first time seeing it!I 100% agree with you on string--recently on Twitter I've seen people use it to make flapping wings and articulated tentacles!
Servo-controlled angry eyebrows sound HILARIOUS!!!I think a stepper motor should work? The only reason I used a continuous servo was because I only had servos on hand, and I used a continuous one so that the strings had something to wind around.
Those are fantastic ideas! I'd love to see if you make it with those modifications!

It's an original design! I also put it on my website (https://www.jasmineflorentine.com/ticklebot) so maybe that's what you're thinking of?
