Do you like that font used in the computer console of old science fiction movies? That font is called OCR and you can actually use it if that is your fancy!
There are two variants of these fonts: OCR-A and OCR-B. These fonts can be obtained here.
To use them, just unzip the files and add them to Ubuntu as described here. You can start using them in any console or application you want.
Tried with: Ubuntu 12.04 LTS
