Electric Sheep with CoagulaLight Sound Equivalents – 1
(Here is a link to view that in high definition.)
I’ve thought it might be cool to combine animations from the Electric Sheep screen saver with sounds roughly correlating to the images – by way of a reverse spectrogram. A spectrogram is a visual representation of the frequency components of something (for example, a sound), so a reverse spectrogram takes an image and breaks it into component frequencies.
The name of one program that does this for sounds (and it can do it from any image) is Coagula, which I used to make representative sounds for this video in 5 second intervals using stills from this short video to showcase the idea. I then combined these all in a Nonlinear Editor (for video) and rendered the results out to this.
The synthetic sounds Cougula makes generally sound scary, screechy, and creepy – especially with source images like this 
I like it.
