This is a short about the cycle of life... more or less. So I guess that's why it's called ◯ (Do not mistake with The Big O, which is another anime) It will take you just one minute, if you're bored and you like watching random animations on YouTube, you might like this. The short was really unusual, probably made by someone high on a certain substance, but it is well animated nonetheless, although it's really difficult, if not impossible to make any sense of it; anyway, this won't matter much, you might as well appreciate the awesome piano piece in the background that synchronizes with theanimation.
