Wooden Speedometer for a Cat Exercise Wheel [video]

This is fascinating, I really enjoyed it. I found it crazy too. All the fine details done with wood.

For some reason, the video also reminded me of the blind watchmaker parable https://en.wikipedia.org/wiki/The_Blind_Watchmaker. There was a recent submission about it https://news.ycombinator.com/item?id=40379784

It is hard to believe for me that blind coincidences in time will be able to create an apparatus like this. There needs to be a designer, although not necessarily god.
