/* Sebastian Molano - a portfolio at night.
   The page is a dark room and the work is what is lit in it: air over a wing,
   a machine drawn and then made, physics glowing out of the dark, a world of
   printed metal seen through a beam of light, the earlier works alive in their
   rooms, and the night sky. Motion is slow on purpose; everything that moves is transform or
   opacity, and nothing moves while it is out of sight. */
