I decided to set a basic challenge for myself - to design a display system based on a 3x3x3 isometric cube.
The two main rules that I identified were that:
• all characters must fit within the 3x3x3 cube (even wide letters such as M and W)
• each character must only use two faces to describe itself (effectively forming a 3x5 grid to work within - because the edge between the two faces operates as a single row of 3D cubes)
The M and the W were certainly the hardest to describe with such a low resolution, but they can be deciphered in context.
Anyway, here's how they came out.
