We explore two of Ron Graham's passions—juggling patterns and perfect
card shuffling—through one of our passions, mathematical fonts. First,
for each letter of the English alphabet, we design a one-person three-ball
juggling pattern where the balls trace out the letter (possibly
rotated 90°). Second, using a deck of 26 cards labeled A through Z,
we show how to perform a sequence of in/out perfect riffle shuffles to display
any desired sequence of letters (forming a word, phrase, etc.), using
algorithms already developed by Diaconis and Graham. Along the way, we pose
some new open problems about perfect shuffling.
