An old updated idea: overlapping glyphs, and 3D simulation with colours. See also zupra eYe/FS.
Based on a 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. (Edit: apparently it's called Bessellen)
Now updated to be closer to the original, plus added kerning.
Spray.ME is a classic stencil typeface, a bit inspired by Impact, but with a little twist. Hold Shift while typing for a dirty effect of fresh paint dripping from the letters. Stains, splatters - just like it was sprayed a few seconds ago. "!" hides behind "\" and "|".
I realize that there are tiny holes scattered over letters with the paint effect, if this font is going to be disqualified for that, I can remove them. :3
Ah - there's a tiny spray can dingbat!
