Remember Jurassic Park? Remember the, "Ah Ah Ah! You didn't say the magic word!" animation that plays when Samuel L. Jackson tries to undo Newman's hacking? It's that. It's just a small little program that plays that...

Psychedelia lets you choose a pattern and lets you move the mouse across the screen.  The pattern animates in B&W around your cursor's position. Psychedelia 1.4 comes with 13 animated patterns.  

Bahaus is what looks like a demo.  It draws rectangles of various sizes at random positions, alterning between B&W.  Clicking exists.  There doesn't seem to be anything else about it.

GomerFun renders a couple colorful patterns across the entire screen (altough, since resolutions in 1986 were not that high, some patterns obviously won't fill 1024x768).  Not much information available on this very old piece of software,...

Brooke looks like a simple demo where a scanned female face blinks her eyes.  There doesn't seem to be anything else to it, no about screen, version info or anything at all.  

Bouncing Black Square is an extremely simple 1.2KB app that only displays a big square that bounces on the edges of the screen.  Not sure if it was meant to be used as a screensaver or as a demo.  There is nothing else, no menu, no about...
