Our lives are so full of "little black boxes" that hide from us a level of complexity that few of us truly grasp. This is a HeNe (Helium-Neon) Laser refracted across some PC-104 hardware, with a touch of dry ice to highlight the beam. The speckled nature of the red areas is inherent to laser light.
This little gecko looks calm and cheeky, but his heart was racing! He had just had a memorable drive to the shops and back, riding on the roof of my car. Good thing his little feet are very, very grippy! :-)
