A true story: I needed a picture of a combination lock, so I drew one.
Would you believe it took me an hour and a half just to to draw the loop? I'm pretty sure nobody's going to see this and say, wow, that artist sure got the lock loop right. There's no Lock Loop Hall Of Fame. And in Vegas, someone took a bath on the over/under for lock loop rendering time, or at least the alternate universe Las Vegas where it's common to bet on art.
