I hate the idea of revivals. I have publicly said I choose not to do revivals because they make me uncomfortable. This is as close as I have been to crossing my own line. To be direct, Rhythm is based on the ATF typeface, Ratio (I just recently learned the foundry of origin). I came across this typeface from a printed specimen years ago when I was in school and held onto it. It was unique and I loved how well integrated the inline worked within both the flourish and serif of the glyphs—it was old, but not, reminiscent, but fresh.
