Since this blog has been a bit quiet lately, here's another Hot Font. This one is called Muli.
Muli is a display font, yet works well on many different things. Muli comes as regular (Normal 400) and light (Book 300). It's clear, simple and lightweight sans-serif. Created by Vernon Adams as many other Hot Fonts, Muli is published under SIL Open Font License (OFL) and it's of course free.
