Not truly finished; not truly in line with the rules of the contest, but it is what it is.  NOTE: To avoid burst eardrums, don't forget to turn down your volume before you leave the kaleidoscope room.  Beyond the room after the kaleidoscope room, there is no sound.  And, just so that you're not surprised, it will dump you out of the program after the river room.
