Steradian

Steradian is an exploration of the geometric genre and although it has a geometric base, the widths between letters are not much different across the weights. That is due to the process, in which the proportions of the heavier weights paved the way for the lighter ones. It also has a series of details that make Steradian stand out and gives it ...
