The letters in Bouncer are round because they all begin as a ball and then have parts of the ball cut away. Bouncer was one of the earliest typefaces from Ingrimayne Type. Lower-case letters are smaller versions of the upper-case letters.
BouncerTwo, designed twenty years after the original Bouncer, continues playing with the idea of making letters by cutting out parts of a circle, but in this case the circles are interlocking. All letters are upper-case but some of those on the lower-case keys differ from those on the upper-case keys. BouncerTwo is eye-catching but not highly legible.
