With licences galore wrapped up with the originator of the whole idea, Xerox Corp, AT&T Co and Sun Microsystems really don’t have to worry too much about look-and-feel suits over their Open Look user interface for Unix from Apple Computer or anyone else, but they have come up with the odd original idea anyway, such as electronic drawing pins (thumb tacks to our transatlantic cousins) to pin important menus to the screen for further reference, and an elevator to move up or down in the text: since Apple’s suit says that it is the Macintosh’s audio-visual user interface it wants to protect, just to be on the safe side, we recommend to anyone else wanting to do a similar user interface that instead of using a mouse that clicks, they should go for one that squeaks.
