This is 15, 1-minute long animated shorts by a variety of Japanese animators. For the most part they seem kind of pointless, some trifling idea the animator had. Some are like a one minute clip from a movie, some are just images.
A handful are quite good. There's a low-budget invasion that's amusing, a sweet one centered around a weird rollercoaster ride, a goofy one about a thing trying to distract a guy. I think I liked those not just because they were well done but also because they were full, 1-minute pieces rather than sketched out ideas or bits of imagery.
Some people like bits of imagery, so they're likely to enjoy this more than I did.
