Designed by Robert Schenk, TOCinRings is a monograms, novelty and typewriter font published by Ingrimayne Type.
TOCinRings has letters in circles. The letters are from a typewriter font called TiredOfCourier.
The typeface contains characters that can add color to letters. There are two ways to do this. One uses layers and the other a combination of characters, some with zero width. A collateral pdf file explains the how this can be done.
