This is a joke website that pretends to provide a live TV Barrandov feed but instead of the video, there is a JS canvas simulating a TV test pattern as broadcast on the morning of January 20th, hence the title Monoskop JS (not affiliated with a person with initials JS, no lawsuits pls).
This page is in progress, it will be replaced with one that resembles an actual modern website. That will be generated with Wordpress or something, I made the iframe below from scratch and I don't feel like writing all the HTML/JS/CSS manually anymore. I learnt a lot, though.
