Stable diffusion art with no prompt

What happens if you ask the stable diffusion AI tool to generate images with absolutely no prompt at all?

On my system that I have running stable diffusion here I’ve been experimenting with different prompts and styles and I got to wondering, what happens if you give it no prompt at all. Most online tools won’t allow it (and let’s face it, they shouldn’t) but running my own system lets me do such things.

So, what happens if you do run it with no prompt at all.
