Long time ago when I was just learning to do 3D animation I decided to make a rather complicated scene to practice. Then I've done a lot of mistakes, half of what he wanted I could not realize, and that I could partially not work. Back then the render of one frame took me 20 minutes so I abandoned the idea to render this animation, now the frame takes me 5 minutes, so I decided to do it all the same as some frames even turned out not bad, although basically the animation is pretty mediocre.
