Another project for school.  Basically, I took a big box, painted the inside white, and pasted a bunch of cutout stairs inside the whole thing.  Then I took shattered pieces of mirrors, stuck those in different places, and cut a small hole in the box where a light could shine through.  I also created a sound environment which I thought suitable for the inside of the box.  So, you put headphones on, stuck your head in the box, and listened while observing the stairs and mirrors.  The result was a somewhat disorienting experience that reminded me of a cross between and Escher painting and the scene of stairs in the castle from the movie The Labyrinth.

Below is a pic that resembles the inside of the box.
