During my latest researches I found this video of an exceptional animated short film made and written by Kealan O´Rourke in 2005.
A little shadow creature in the night is melancholic and lonely, because he feels different than the other shadow creatures. Than suddenly he discovers something, he never saw before, and this will change his life.
This little love story is so beautifuly made, that I had some tears in my eyes at the end.
I highly recommend to watch it!
