Majör Mono is a monospaced geometric all-uppercase sans serif typeface which also has a complete set of constructivist display characters with a playful attitude.
Majör Mono has many stylistic alternates but the basic variation between serious/playful faces can be implemented on web use where OpenType features can be hard to apply, thanks to the fact that the sans serif and the display versions of the letterforms can be reached via lowercase and uppercase options. This makes Majör Mono a great choice for web typography, especially as a big point-size player.
