The Geneva Mechanism is one of my favourites:

Not as pretty but always interesting

I went through a phase years ago (ok, almost 20) when I got a little obsessed with building mechanical oscillators with chaotic orbits.

Wintergatan

the "how it works" videos explain the maddening genius behind it.

re: walking bikes; have a look at Karel Zeman's movies; I think he had one of these in "the stolen airship."

Also, Jos de Vink makes very cool artistic heat engines:

The Wintergatan Marble Machine is very impressive! Coolest finding of 2016!

Speaking of marbles, Matthias Wandel built a rudimentary digital computer out of wood. The ingenious Binary Marble Adding Machine is, basically, a 6-bit adder that runs on gravity and uses mechanical flip-flops for memory storage.

Here's a video of the Binary Marble Adding Machine.

Rod, you and a CNC machine would be a dangerous combination.
