Strange that nobody on this thread shared the amazing eDEX-UI project: https://github.com/GitSquared/edex-ui. A full open-source sci-fi terminal emulator inspired by Tron Legacy.
Hah yeah I remember downloading that and reading the disclaimer that you shouldn't do any real work on this seeing as how it has a virtual keyboard showing your password keypresses, scifi UIs are cool but not practical at all.
