Single Project Help Needed

Morning Blender Heads!
Working on a single project for Virtual World object.
Quick Overview:
Dome Roof (Sphere) cut in half, inside will contain solid black with pictures in triangles. The Outside will remain a solid Black.
Want to create, or find Lighting script that randomly lights an individual triangle (Pics) every few seconds.
This is for an Adult club build in an Opensim Grid / Virtual World. Adult Content will be visible.

This will project will have 3 parts:

  1. The physical build itself
  2. The graphics – Using Photoshop
  3. The scripting
    Background on myself:
    Beginner – know just enough to be dangerous!
