Odd browser tab trick for inconsequential variations

By accident I discovered a simple way to do minor variations on a theme.

It started when I plugged in the following prompt:

I was really pleased with the results, so I wanted to preserve them and thus decided on a whim to leave them alone in their tab and experiment in another tab.

I copied the address....

... and punched it into a new tab. Expecting to see four different results, I was completely blown away to see... results that are strikingly similar to the original four results, but ever so subtlely different.

Naturally, I did it 8 more times just for kicks.

I don't know what to make of all this, but here it is for any of y'all to thin about and play with.
