fiber optic lightshow

Did you ever lean back in your seat at school and look at the ceiling… and wonder what it would be like if lights were on the floor and desks were stuck to the ceiling? I used to imagine walking on particleboard (being careful not to step on the long fluorescent lights) while wondering if the glue that secured the furniture to the ceiling was actually strong enough. I thought it would be neat to decorate a room like that–or at least make a walk-through art installation of it.

When I look at this photo, I see some sort of otherworldly scenario, with waist-high anemones sprouting from the floor, and an undulating cave of light formed by some incredible natural phenomenon. What do you see?
