For very different reasons, I also like this terminal. It simulates using computers of old. It is particularly funny, not real useful, but funny to use a modern computer of which is emulating a display where the horizontal sync requires adjustment.
Install on openSUSE
sudo zypper in cool-retro-term
This is quite possibly the coolest terminal application I have ever used. It is not all practical but if you want to revisit working on an Amber phosphorus CRT from 1987, you can.
