Yeah I tried to make the video as trippy and ridiculously over-the-top as possible, haha.
And you're right, the ASCII characters ARE blending into a human figure. Or rather, the program I used to make the video took a source file of a human body, and turned it into ASCII characters. What's really cool is that you can connect the size of the characters to a MIDI controller like modulation, or volume, or pitch bend, and it'll make the numbers get smaller (and thusly look more like the original image). Which is what I did, at one point.
