Subsurface Laser 3D Imagery of Authentic NASA Spacecraft in Glass
Using high-frequency lasers driven by hand-tooled software, each optically clear glass cube boasts a highly-detailed rendering of an iconic American spacecraft. The engineering designs of the spacecraft laser-etched within these cubes are taken directly from the authentic NASA 3D blueprints. Best viewed against a dark backdrop, we highly recommend the separate purchase of the lighted base (with 4 built-in LEDs) for optimal display. Each beveled glass cube measures 2 ⅜” (60mm).
The Science behind the Art:
The 3D images are made of tiny fractures created by lasers: the beam shines into the glass without damaging it except at one focal point, where enough heat is created to crack the glass. These microfractures are about .1mm long, and they're pin-shaped rather than round, which you can see as you turn the glass pieces: the designs are sharper and dimmer in one axis, brighter and fuzzier in the other two. To draw many points the beam is pulsed on and off, and repositioned by moving a CNC mirror. These designs use a few hundred thousand points.
