The UI is not the most intuitive and variables has been named badly - sorry for that.
You may want to switch "randomize" off, so all variables are in use. Try out frepeatx and frepeaty, while randomization is on.
After switching off randomness I immediately felt calmer due to the smoothly changing faces.
Genuinely curious, I know it sounds like I'm demeaning. I really am not trying to!
Got a contact?
If the random feature adjusted the settings then it might be a bit more acceptable but leaving them the same whilst drawing a dramatically different face breaks their "control" nature.
Once random is off, it's great fun!
I've tried to make something like this as well, but I've probably aimed too high art-wise :) I really like the style of your generator.
I've have also made other kind of experiments with face generation: https://github.com/aleksimyllyoja/generative/blob/master/img...
My initial reaction was one of revulsion ("Why do they need to meddle with everything") but after taking a few moments to calm down I realised I could get used to that change.
I think to make it attractive, I would want a quick way to switch between behaviours when I need them. From what I can see, the change between 'long press' and 'key repeat' is effected by launching Terminal, making a configuration change and restarting the machine. I find this unappealing.
I wish all the controls work with randomize on – so I can have random image with some parameters fixed. e.g., if I change some parameter, it stays fixed.
Do you have source code for the project?
Once again, it's awesome!
