IngrimayneType has put letters inside a variety of objects, including bowling pins, book covers, coffee mugs, teapots, pumpkins, Christmas ornaments, train cars, tombstones, old bottles, circles, and rectangles. In each case the letters were placed on a single shape. The use of the Opentype feature of contextual alternatives makes it easy to use two different but alternating shapes. ButterflyWingz puts its letters on the right and left wings of a butterfly. The wings provide a large surface for drawing letters, but they have a odd shape so letters must be distorted to fit. The wings are symmetrical but some letters are not, so the right and left wing versions of the same letter are sometimes quite different. Without the contextual alternative feature one could design a typeface like ButterflyWingz but the user would have to alternate upper and lower case keys. With contextual alternatives turned on, the computer automatically alternates the letters creating a line of complete butterflies. Turning on the Opentype feature stylistic styles one (ss01) replaces the empty spaces with empty wings. However, sometimes an empty wing at the end of a line is unwanted and it can be removed by changing the typeface or by turning off the stylistic style for that character. The family contains two styles, a filled style and an outline style. They can be used separately or together in layers to add color. (Empty wings are on the logicalnot and registered characters.) ButterflyWingz is hard to read and should be used in small doses for decorative effects.
