Great points and questions! All of them work well on the lock screen, but some of them work better than others on home screens with apps. I was surprised at the force of my own aesthetic preferences: I moved and re/dis-organized my apps so that they didn’t interfere with the wallpaper’s text.
Now you have me wondering if perhaps a different series of wallpapers would be good for home screens. These wallpapers send the message of “Don’t unlock your phone.” Home screen wallpapers could send the message of “Ok, you’re here, but, like….don’t stay here long.” Not quite as inspiring, maybe, but something for me to think about.
