It is an optical illusion and impossible to be build. There is a well known painting of staircase going in every direction and even upside down but all connected to the other. I don't remember the painting or the artist.
Thanks. I knew someone would know.
I understand that this "must" be a hoax, but the continuous video with no apparent cuts, the camera angles looking up the stairwell to see the person going up and away, only to pan down to see the same person "immediately" coming up and towards the camera, only shows the "trick" to be legitimate. And the people holding hands continuously and each person being higher or lower than the person next to them, only adds to the "magic".

This is from a contributor in answer to the question about this stairwell... evidently he was at this event...

The secret is that it's a film maker's illusion, in reality it's impossible in 3 dimensions. I was one of the around 30,000 people at the "Imagine RIT" festival on May 4. I had noticed the Escherian stairwell in the list of exhibits and realized that it couldn't be "real" but was interested in seeing what it was all about. There were signs pointing to the Escherian stairwell all over campus but we soon realized that they were pointing in random directions. We finally found the classroom where the film maker played the video seen on the Internet plus a shorter one where he explained that it was his master's project and what he was trying to accomplish. He also gave a short live talk and answered questions. Nobody in the showing that I went to asked about how it was actually accomplished but it was obviously just clever editing.
I guess it's the only "logical" answer.

There are a couple of clues inside the video that point to the fact that it is a hoax. It was well done, though, and while it might have been improved with a Hollywood prop manager it does fool one at first glance.
Clue #1 - From the original view, you see the person walk up the stairs before re-appearing a half flight below. The wall at the end of the half-flight up has no light fixture. The wall at the end of the half-flight down has a florescent tube that should be extending to the first. It doesn't.
Good catch... were you ever in photo recon interpretation?
R.I.T. is a pretty good school. You may remember that their hockey team made it to the Frozen Four (NCAA hockey version of the Final Four) a few years ago after just 5 years of competition.
