In the February 2017 issue of Linux Magazine (in the Linux Voice section), there was mention of Cool-Retro-Term. It gives you a terminal emulator that tries to duplicate the experience of using an old cathode ray tube monitor. But I also noticed that it comes with a dmg for installing on macOS.
And since I like a bit of retro technology, I couldn't resist trying it out. So I went a put a copy on my MacBook Pro. It really is quite cool looking, and visually reproduces an ancient monitor quite well. It even has the bend at the edge of the screen. Personally, I've turned off the glow line feature because I found it distracting. I have also made the font smaller, so that I can get more text on the screen - that's probably cheating - but it made the terminal more usable. Currently, I'm using the Apple II font from 1977.
Here I am using it to mess about with streaming radio from Madplay on one of my routers running OpenWrt:
It was really simple to install on macOS, and it really does faithfully reproduce the monitors from the old days. It's good nostalgic fun.
