I released That Secret Feeling on February 17, 2010. The typeface was composed only of the shadows of a cartoon bubble style, without the solid letterforms themselves. The design was inspired by a poster for UFO, a short-lived psychedelic dance club in London during the 1960s.
I made the typeface available exclusively to my Twitter followers at the time, using it as a limited distribution experiment. For a decade, it was not available through other channels.
That Secret Feeling was initially distributed with a free commercial desktop license. In August 2020, I placed it into the public domain.
