To view QuickTime animations directly within a Netscape or Internet Explorer browser window, download the QuickTime Plug-in 1.1 for Macintosh, Windows 3.1, or Windows95/NT; OS/2 users can use the QuickFlick plug-in for Netscape Navigator.
To spawn an external viewer to view QuickTime animations, UNIX users can use the application XAnim (select the "QuickTime Animation" link above).
