Do you know what it's like to be a tree?

Whilst taking a breather, i came across on youtube something interesting and as quoted;

A rotoscoped animation using unscripted footage from a hike in the woods with my 8 year old brother Julian. I rotoscoped it by hand drawing every frame, using a wacom tablet, even the titles. If you have time, visit my illustration website at http://vocaleyes.com/benarthur/

Sometimes my job makes me feel as if i am a tree.

But it makes me wonder what i was in my past life? Possibly a butterfly?
