I played a game of 40k recently that required objective markers that had variable points.
After scrabbling around with pieces of paper and a pen I decided to make my own.
These are cut from two layers of 1mm thick cardboard glued together.
The top layer has a generic glyph on it.
The bottom layer has the points value of the objective in decimal and in binary.
If the font looks familiar, it is a freeware version of the Terminator font.
How could I not use that?
