Type In Space for HoloLens 2
Type is beautiful in mixed reality. Type In Space for HoloLens 2 lets you interact directly with letterforms and compose typography in physical space using fully articulated hand tracking.
Typography Insight
“Anyone who loves books, words, history, or fine art — even in the slightest bit — will find Typography Insight as intoxicating as Wikipedia and as fun as a video game.”
Fast Company
“The app isn’t a dull list of typefaces. It’s excitingly interactive, enabling you to experiment with kerning to see how it transforms the way text looks, and to compare the same characters in different typefaces.”
