MuirMcNeil Worm is a modular type system designed in seven compatible weights.

Each Worm glyph has been shaped individually rather than being predetermined as the product of an overarching design code. The result is a type family that is co-ordinated as a loose association of idiosyncratic characters rather than a strictly regimented alphabet. However, the Worm letterforms are balanced harmoniously as a system by means of a consistent geometric framework that determines the construction of every contour, space and alignment.
