A non standard stencil/piano-like font, using an experimental "guides + nudging" kerning process and a lot of smooth curvy shapes. Some soft alternates (for A, W, w, X, x, Y and y) are in the ligatures area at the More Latin section.This is a clone
Bevel/chisel effect using connecting bricks.
Glyphs B,K,R,S,X,Z,k,s,x,z,2,3,5,7,8 miss cuts because of nudging space limitations.
I was thinking of something else and the thought "go forth and multiply" came to mind.
The word forth brought to mind 4th, with the 4 fully formed as seen here. So it had to be done. In the process, I've made the personal best smoothest fake circle yet on fontstruct, backed by a pixel-by-pixel matching of a real approximated circle in Ai.
An experiment with propellers. It seems to me like something four would make. Suggestions are welcome. Thanks.
02/08/17: Thanks to the new Kerning feature, a separate "r" is no longer required. Also made the rings a little rounder and fixed the rings on U and u.
