Ortho-type is a very intriguing concept for typeface design. I think it takes the idea of multiple master and perhaps open typeface to a new practical level. It’s described as “An experiment in dimensional typography” at processing.org which it is, but it offers some very interesting tangibles if it were released today. Most typefaces when manually stretched and compressed look awful. However with ortho-type, the distortion always seems in proportion. Ortho-type could work really well as a display and information typeface where space could be limited. As a three dimension space, it would be put to best use on a monitor. The only question would be on how it translates to smaller sizes like unibody 8.
