Visix Software Inc has now begun shipments of its Looking Glass graphical interface system, and has set the official launch of the software for the second day of Unix Expo. Visix has been under development for five years, and includes sophisticated mechanisms for automatically identifying types of files and presenting them as icons. But vice-president of marketing George Hoyem said that Looking Glass should not be pigeon-holed as simply a high-end product: it is to be offered by Interactive Systems Corp as a graphical interface for 386/ix, and was recently the subject of further deals for use on X terminals. Intergraph Corp will also use Looking Glass for its X Window and Environ V-based workstations, and Hoyem said that three further endorsements were waiting to be signed.
