This was taken at the McNamara Alumni Center at the University of Minnesota.  The building is full of lines, angled ceilings and angled windows and is a photographer's dream for finding interesting shots.  The marble "floor" you see is actually raised up about 2 feet from the regular floor and is covered with about 1/4 inch of running water, which falls over the edge into  a narrow reservoir.  Makes for some good reflections!  My son tells me there is another of these waterfalls just like it outside--but right now it is covered with snow!
