Those are supposedly monkeys. Giant inflatable albino monkeys. In blackface, for some strange reason.
I'm told they're supposed to be art, and that they're affiliated with the 21C museum/hotel across the street.
I don't know whether giant inflatable albino monkeys in blackface are art or not. What I do know is that (a) They seem kinda rascist to me, and (b) That's a busy interstate highway behind them, and (c) If I were driving down the highway and saw giant inflatable albino monkeys in blackface, I might just cause a 50-car pileup.
Maybe that's where the art would really be.
