Optical illusion or freedom of expression?

A couple of days ago, a friend sent me some pictures titled ‘body-art’.

At the Sunday market, I found a vcd on Woodstock 1999. Some of the topless women were painted in a similar fashion. What a coincidence.

I found clips of some of the women and men who were topless and bottomless amusing and the whites were used to them. But I still could not get over the last performance in the vcd showing a blonde male guitarist of Red Hot Chili Peppers, stark naked with only his guitar over his private part. When they finished the song, it was shown clearly that he was in fact naked! Fast forward to now, I wonder what else to shock the audience.
