Only a monster would build something that forced you to type in comic sans. I have nightmares of this. They usually end with me being run off the Internet with pitchforks.
This is from horror designer Jesse England, who describes it thusly:
Sincerity Machine: The Comic Sans typewriter was made after viewing a document with a typewriter font present in it; I realized there was nothing stopping me from altering a typewriter to write in a different font. I used a laser engraving machine to etch new letters out of acrylic, and glued them onto the strikers of a 70's era, Sears-branded Brother Charger 11 typewriter, which I found in the street a couple years ago. I also used a vinyl cutter to make new key covers as well.
As part of my ongoing thesis of questioning how we create, consume, store (and fetishize) media, it's my wish that a classic, functioning typewriter altered to write in the most popularly despised font of modern times will provoke thoughts about such media concerns.
The name "Sincerity Machine" comes from a Cat and Girl comic strip by Dorothy Gambrell.
He's said that while he's not a huge fan of the font, he does think it gets a bad rap. Which, it may well do, but it's a little late to turn the tide of public opinion now. It's not just a font that people hate, it's a font that only the brave dare use.
