I've been searching for this animation years ago.
I watched it when i was like between 7 and 9yo (i am 21 right now) and i had it stuck in my mind since then. For me this was something extremely scary.
Don't know why or how it shocked me that much at that time, right now it doesn't shock me at all.
But still, it is an amazing work.
I'm really glad to have finally found it, i have waited so much to see it again.
LOVED IT!
