Sorry for this video.
The idea was born while listening to this Song on a trip all over Bolivia when I managed to capture my brother's PSP. The concept came from my admiration of the masturbation-scene of the old Evangelion movie met with me trying to paraphrase the song.
Again this one uses motion-interpolation for a lot of things, including 60 fps output. The video is only optimized for 60fps, so I recommend to watch that version.
If you're confused about the video's title, I used it for a lot of cool parallel properties to the video. Besides the obvious relation of "Tangent" - "Touch", the gradient of tan(x) is always positive, but the function is still periodic and doesn't change it's value averaged over one period at all. Also, I don't exactly hate maths

And here is the video without effects on YouTube, and on Mediafire.
