My eyes can't decide what is foreground and what is background. I think it all depends on the edges: when the black is further up the edge, white is foreground.

everything you make is incredible!
u/danny@hille.dk

Very nice. It kind of looks like a late-70s magazine ad. Pacman and drugs—your kids will love them!
u/cantelope

danny, sarcastic 'drugs for [your] kids' remarks and judgement about others' "sins" is all well outside the scope of this platform. Might want to get back to building and being supportive
