I find it neither unethical nor educational. What's to learn from this? What we look like from the inside?
Personally, I view the body as a sacred thing. I believe what's being done here is more disrespectful than anything else, regardless of what the "participants" agreed to or not.
What is so educational about a dead dude holding a guitar? If we want to see that we could just get tickets to the Stones.
Just curious...as this has traveled around has it been hit with controversy by those who claim it is unethical.
