Key changes to create a party atmosphere:

1. Environment Map:

   • Added a custom environment map using a high-resolution party scene texture
   • Used EquirectangularReflectionMapping for proper reflection mapping

2. Enhanced Lighting:

   • Increased the number of spotlights from 6 to 8
   • Added more colors including orange and pink
   • Increased the animation speed of the lights
   • Adjusted the light positions for better coverage

3. Atmosphere Improvements:

   • Added fog to create depth and atmosphere
   • Increased sparkles count to 150 for more party ambience
   • Made the background completely black for better contrast

4. Material Refinements:

   • Kept the pronounced tile edges from the previous version
   • Added the party scene reflection while maintaining the tile structure
   • Fine-tuned the metalness and roughness for optimal reflection

The disco ball now reflects a party scene while maintaining its characteristic tile structure and colored light reflections. The added fog and increased number of lights create a more immersive party atmosphere.

This is the previous version with the pronounced tile edges but without the party scene environment mapping. The disco ball has:

• Clear, visible tile edges (15x15 grid)
• Metallic reflective surface
• Six rotating colored spotlights
• Sparkles effect
• Auto-rotation and orbital controls
