Bar Graph and Maze
The demo shows a mockup window system. Each "window" is actually an individual program - each run one at a time from a batch file. When the program is done it exits leaving the image on the screen. The next program run may or may not save what is behind its window to be restored later.

The above screen shot shows an animated bar graph that is followed by a mouse that runs through a maze.

Pusher
Then this guy comes on the screen and slides the screen away.

Perq Sketch
A scripted demo of a paint program plays back the actions of someone drawing this face.

Bouncing Blocks
Bouncing blocks, lines, and moving windows.

Keep in mind the Perq added hardware and special operations to accelerate manipulation of graphics on the screen. This was much faster than software directly manipulating the video memory, and in some ways made GUIs more practical

Fonts and a Squirrel
A demonstration of different fonts, sizes, and styles.  Oh, and a squirrel!
