Virtual

Virtual 1.61 is an application that allows you to pretend you have more than one monitor. In a little window, it draws as many virtual screens as you like, and the windows of open applications inside them. When you instruct Virtual to switch virtual screens, it moves the application windows so as to give you the illusion of working on the new virtual screen. Virtual allows you to do a great deal besides switching screens. You can move your windows around by dragging their representations in Virtual, place them in different virtual screens to organize them in work groups, make some windows sticky, or assign whole applications in a particular virtual screen. VirtualDog is a companion extension that communicates with Virtual to make applications open their windows on the virtual screen of your choosing.

This version is both for the PPC and 68K machines.
