Are there any similar applications for Ubuntu?
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.)
