00ne Fuse, created by neurone error for FSI FontShop International GmbH, is a free geometric pictogram font. Its pictograms use solid, blocky silhouettes, stepped corners, and cut interior symbols. The forms feel blunt and mechanical.
Signage is its clearest role, especially in technical exhibits or industrial-themed spaces. The compressed icons suit game interfaces, electronic music graphics, and event wayfinding. Their cutout construction echoes switches, panels, and schematic illustrations, so the symbols can form part of a graphic interface.
