Sergei Godovalov’s Bashkir inspired geometric typeface. This type has some really interesting use of serifs that makes this quite unique.
Krisijanis Mezulis from Wild Ones Design is offering a free brush font.
Kimchi Lee is offering a free humanist typeface inspired by her culture and its history.
These are free typefaces with visual features commonly seen in Sci-Fi. Suitable as display faces, they would work perfectly in visually establishing the theme of a project.
As the name of the typeface implies, this looks and feels laid-back. As a body type, some added leading and tracking will probably improve readability. And as a display face, giving it enough room to breath will give that casual look.
