One of the things that I have learned doing the lunar lander dwelling project is how much I like to use “magical” light. By not charging the rock star design fees, I only do the standard scope of work, not the frosting, being like most boat designers. My lighting design has been workmanlike.
Light can make any multi a magical place. The ill fated Estonian powercat project had some tricky lighting in the renderings. Greg Lynn used acrylic’s light piping very effectively on his tri design.
On the lunar lander I have used; recessed lighting, glow powder in epoxy, light piping with acrylic, and the temperature indicating shower head light shown. No electricity involved for the temperature indicating lights on the showerhead. Did I ever mention that I love this stuff?
