GODDAMMIT RED!
i started doing something like this while i was at work a couple of days ago & emailed it too myself with the intention of finishing it but never got around to it. good show thus far though. and there's bits i'll add once i do get the visual demonstrations all figured out!
as for vanishing points that aren't on the horizon: yes & no. instead of thinking of the horizon as THE horizon, think of it more like an 'eye-line' and not only do you have a horizontal eye-line, when you start dealing with multiple point (3 & higher) perspectives, you start having a vertical eye-line as well. and vanishing points can situate along that too. so yeah, they don't have to be on the horizon, but they all converge along the eye-lines. if any of that makes sense.
