Begin a new game and go into Atrus' study. Click on everything in the room that resembles a pepper shaker. Once this has been done, link to J'nanin. Use the light reflectors and reflect the light over to the green and red reflectors. Go across the island to the green and red reflectors. Turn the green reflector so the light reflects to the red one. Go up the stone steps to the red reflector. Stay here and do not move forward yet. The red reflector reflects the light in two different directions -- over to the yellow reflector, and onto a big rock that is directly in front of it. You should be facing this rock now. Reflect the light on the rock. Hold ~ and click forward once (toward the rock). If done correctly, you will see a projection of the face of a cat named Pepper. He belongs to one of the programmers.
