This is a fascinating case study in AI. What do you think is the most common thing a person would start to draw on this system? If you said a penis, it looks like you'd be correct. By the time I came across this site, anything I started to draw (a sun, star, basketball hoop) was magically transformed into a penis.
Everything is indeed a penis.
Wait, so it's actually trained on user drawings? I honestly thought it was someone trying to play a prank on us.
Everything you draw turns into a penis. Either 99% of people are a bad influence or the authors are trolling.
