Helium/Gold is an experimental variable font with extreme width contrast.

Named after two chemical elements known for their respective light and heavy weights, Helium/Gold started out as some simple custom lettering for another project, before developing into a complete three-master typeface.

In its intermediate weights, He/Au is a solid display sans with a slightly cyberpunk aesthetic. At either end of its broad spectrum, it becomes something entirely different: at its most condensed, an oddly-proportioned barcode; at its most extended, a dense space-filler with minimal legibility.
