There's a new short film (online!) used by its writer/director to show how an arbitrary decision in one life can have a big effect generations later. Link.

The example he uses is of Felix Vinatieri, Col Custer's bandmaster, not being at Little Bighorn, and thus surviving to sire the Vinatieri line that directly led to Adam Vinatieri. Then they manage to tie-in SB XXXVI in a semi-factual, semi-fantasy short flick. (Resulting movie poster is hilarlious.)

Cooky, but interesting. Here's the news item about it, too. The writer/director says: "Adam's great-great-grandfather Felix Vinatieri and his 7th Cavalry Band were on their way to the Little Bighorn with Custer when, at the last minute, they were ordered to stay behind. If Felix had died there, Adam would not have been born. I thought that story was a poignant commentary about how tenuous life is, and that a path taken -- or not taken -- by a person can have an effect generations later. I combined this with the theory of quantum entanglement -- that there are alternate universes and what happens in one may affect what happens in another."
