Hey folks!
As the author of this, I'm touched by your kind words in the comments!
I feel like I should quote some of you on the clients' page, because some of these comments really reflect on the reasons I wrote this.
This is the kinda stuff I love, I spent weeks learning how to get a Macintosh Classic online so I could use it as an IRC client. Unfortunately it didn’t last long as the CRT flicker drove me a bit mad, but it was insanely fun project.
Not sure about the Mac Classic, but I've found that 75hz or higher refresh rates reduces eye strain on CRTs. I was able to achieve that with the Powermac 7200 all-in-one recently (though albeit at a lower resolution)
