According to an article published in the Hewlett-Packard Journal, the look and feel of HP-VUE was used when developing the Common Desktop Environment (CDE):[2]
HP is one of four sponsor companies that contributed key technologies and helped to develop CDE (Common Desktop Environment). CDE's consistent look and feel is based on HP's proven and accepted HP VUE technology.
After its release, HP endorsed CDE as the new standard desktop for Unix, and provided documentation and software for migrating VUE customizations to CDE.[2]
