Are there any similar applications for Ubuntu?
There is a new (actually one year old) terminal emulator project that does exactly what you want: cool-retro-term (and I agree, it's really cool!).
Ubuntu users can install it from this ppa:
ppa:bugs-launchpad-net-falkensweb/cool-retro-term or compile it from source:
sudo apt-get install build-essential qmlscene qt5-qmake qt5-default qtdeclarative5-dev qtdeclarative5-controls-plugin qtdeclarative5-qtquick2-plugin libqt5qml-graphicaleffects qtdeclarative5-dialogs-plugin qtdeclarative5-localstorage-plugin qtdeclarative5-window-plugin git clone --recursive https://github.com/Swordfish90/cool-retro-term.git cd cool-retro-term qmake && make ./cool-retro-term
From sil's comment:
Happily, the apple2 screensaver works fine: install the xscreensaver-data-extra package and then run as: /usr/lib/xscreensaver/apple2 -text -fast -program bash
(I copied this into a separate answer because being just a comment I almost miss it. It's just too amazing that this existed for such a long time and very little people knew about it.)
I am big fan of cathode look. But there is no terminal out their made specifically keeping cathode/vintage terminal in mind.
I installed Yakuake (terminal dropdown emulator) and it had the option of customizing its appearance. Select the Green on Black option. This is not so bad.
I guess every terminal, even the one that comes default with Ubuntu have customizing properties. You can always choose a green font,a black backgroud and voilaa!!
