I don't care if it's been done before with teddies...That is still So Awesome! I presume they use the modern balloon method? There was a very amazing pattern of clouds towards the end: like waves breaking on a beach. Only a million times bigger.
I don't think that reverance or respect for the dead needs the dead to be hidden from sight completely. It is the attitude that you bring, as a witness to a dead body, that matters, not the display and witnessing of a dead body, per se.
