RM Teeny by Ray Meadows of FontStruct is a free geometric dingbat font made from solid circular forms. Broad curves meet crisp, right-angled cutouts, giving the symbols the look of compact dials or markers. The construction is blunt and strongly graphic.
It is most convincing in icon sets, where the repeated circle-and-notch idea creates a coherent family. That compact geometry also suits posters, game interfaces, and technology branding. Its clearest role is turning simple circles into recognizable emblem-like symbols.
