eDEX-UI is a fullscreen, cross-platform terminal emulator and system monitor that looks and feels like a sci-fi computer interface.
Heavily inspired from the TRON Legacy movie effects (especially the Board Room sequence), the eDEX-UI project was originally meant to be "DEX-UI with less « art » and more « distributable software »". While keeping a futuristic look and feel, it strives to maintain a certain level of functionality and to be usable in real-life scenarios, with the larger goal of bringing science-fiction UXs to the mainstream.
It might or might not be a joke taken too seriously.
It has an onscreen keyboard which would make it a decent desktop for a touchscreen.
You can also use a theme that doesn't show the keyboard.
