typewriter / computer is an iMovie plug-in that simulates a typewriter or computer 'printing' on your clip. Rather than simply displaying a text message, this plug-in visually writes the message letter for letter. Please note that this is an effect plug-in, not a title (we believe that iMovie's title controls are inadequate for the task). It will therefore also happily run with iMovie 3. The plug-in will emulate anything from a simple typewriter to a computer, complete with various cursors, with or without a background.
