a very good mind bending Sci-Fi Time Travel Short Movie
[Edit 2019-03-10] Oh, there is a bug! I love this video and I've seen it a dozen of times over a few years, and I just noticed: at 16:12 the time travel is launched by the one dude from the future, while the past guy jumps in the machine and waits. This can't be, as it's an ancestry paradox. I can only be solved if the jumper guy launches the time traveling sequence by himself, or with the remote control, as with every other time travel jumps.
