Watch this elegant desktop Stirling engine go over 2000 RPM

YouTuber IAA015 likes to demonstrate fun decorative gadgets for the home and office, like this nicely designed Stirling engine that can reach speeds of over 2,000 revolutions per minute.

He also got his hands on a crowdfunded Aquarius "bending water" desktop fountain (bear with the shutter roll from the out of sync lights):
