Abstract isomorphic animation showing at the Venice International Film Festival, by Mirai Mizue... here's the trailer:
"Using a sheet of graph paper, which is typically used for architectural drawings, I combined straight lines which stretch out in three directions to construct the visual.
I think that original fascination with animation is the limitations. To challenge the limitations, I started creating animation by using minimal elements. Apparently, it looks like computer graphics though it's really digital animation drawn by hand."
