Show HN: Ultra-compatibility demo, Jan 2020; How many browsers can you identify?

I've put together another series of screenshots demonstrating my project's high compatibility across existing Web browsers.

The button with a number in it near the top is a JS-update clock, which happened to be pre-generated to a number ending with 0000. If the clock's number doesn't end in four zeros, that means basic JS support is working, and the clock is updating.

I'll be happy to answer any questions about this project. The code is on GitHub:
