Based on an unknown typeface which was used in the opening credits of The Terminator, The Running Man, Class of 1999, and also used on Robert A. Heinlein's book covers there's a font called Heinlein which is similar. I've been looking for the original for a long time but haven't found it, so I recreated it myself.
