I'm not sure how I stumbled across NightCafe, but I did, and started playing wtih it.
It offers a suite of generators to utilise and while the best and newest require subscription, there's plenty that can be done with the free credits and older or less powerful generators. I've been playing with it for about a week and finding it interesting to see where the programs struggle to accomodate the input.
I'm going to try and put up the one I do daily (it also goes on Reddit)
So, here is my first share:
The prompt was: The dome of a domestic nuclear reactor but it is cap of a button mushroom and the surrounding buildings are also various form of fungi
The generator was Flux.
