only 32 LUTs also made me scratch my head: what kind of useful things can be made with so few components?

Microchip has a web page about "CLB"

https://www.microchip.com/en-us/products/microcontrollers/8-...

It includes a creative demo where your browser apparently gets hooked up with a live video stream of an actual running toy hardware setup of a "CLB demo featuring a European traffic light". It's effectively a finite state machine with two red-yellow-green traffic lights. This minimal setup already consumes 26 of the available 32 units.

Btw: as a European, let me assure you that our intersections usually consist of more than two traffic lights, include a fault state (blinking yellow light), and feature synchronized pedestrian lights on which we mostly stand until they turn green.
