I designed the original Periodic as a pixel font on Fontstruct. As I played with the design, the more I fell in love with it. I like the idea of using the exposed pixel as a design element. Over the past few months, I’ve been tweaking it so that it would work better in print. And I’m using Periodic on my new business cards.
For the final version, I’ve connected the corners and broken the strict pixel grid for some of the special characters. The entire design is monospaced with old style numerals. I’ve also added an oblique version. It’s very readable at small sizes and distinct at display sizes. Get SbB Periodic from the “Download Fonts” section.
