This typeface was developed with the idea of having a 3D feeling but in a really simple and graphic way. For example all the characters from the David Light are single line drawings.
It explore the thin line between 2 and 3 dimensions and the perception of volume. Even if the letters looks very simple, they are all based on a technical drawing so I can built them in 3D.
You can see here a model I made of the letter A.
