MoOLIT

MoOLIT was a graphical user interface library and application programming interface (API) created by Sun and AT&T in an attempt to make a compromise between the two competing look-and-feels for UNIX workstations at the time -- OpenLook and OSF Motif.

The library provided common GUI features such as boxes, menus, lists, buttons, etc., but allowed users to choose which GUI they wanted at runtime. It was a short lived project, as the industry was solidly moving towards Motif as the standard.
