I'm almost certain it's been posted before. If not, a lot of people have seen it. But yeah, it's so impressive.
If you've used the program that's shown in that you'll know how difficult and tedious it would've to create.
I can imagine. You probably have to draw out every line right? I would be waaay too lazy for that kinda thing.
You don't have to draw each line in every single frame but the animation, and at such good quality is stunning.
I've had to make several movies in Flash, and do some projects in it for Computer Apps 2, and I gotta tell ya, like they said up there somewhere, that would take ages to make. Like, I can't even put it in words. I had trouble making a robot's leg move the way I wanted it to in the movies I made, so, idk, the guy's either got massive skill, or he's been working on that for that past year.
