Designed by 8vo in 1994 as part of an invited submission to the American Center of Design Journal, Interact was originally implemented as a system of grid-based lowercase screen fonts which followed a mathematical progression cross-relating pixel resolution to typesize in fixed increments. Interact has recently been updated and extended by MuirMcNeil as a complete system of scaleable Opentype or Truetype font sets. These have been designed to operate both as clean bitmaps for screen or web applications and in print media.
