This is literally my favorite video to watch when in an altered state. The fractal animation is mindblowing and literally takes you on a ride. Plus, this guy syncs the fractal animations with crazy sound effects that match perfectly.
He has a few more of these videos if you look around. Make sure your volume is up and that the video is on the highest resolution possible.
Please watch and let me know what you think. Also, if you all have any favorite videos that are similarly mindblowing – then feel free to share them.
