  • Audio-reactive behavior driven by central system
  • Custom mounting and structural integration

Laser and Optical System

  • Internal laser installation with custom prism for controlled light diffusion
  • Laser mounted inside sculpture
  • Custom blown-glass prism (hand-fabricated)
  • Manual alignment for safe operation in public space
  • Used as a spatial accent, separate from the core media logic
Optical laser system component
Custom speaker pillar structures — architectural drawing
Subwoofer enclosure drawing

Spatial Audio System
