The point isn't showing what they look like, it's that the result is randomized. Screenshots aren't, so that kind of defeats the purpose. The article starts with instructions on how to actually see and interact with the demos (the easiest is to use [Polypane](https://polypane.app)), as well as a video showing all the demos from the article running in Polypane. - Source: Hacker News / 30 days ago

Is this for remote access VPN? If so, what kind of bandwidth are you seeing on a speed test site like fast.com (with the VPN off) compared to the VPN bandwidth you're experiencing? Source: over 2 years ago
