Please prove my 12 year old brother wrong!!!!!!!!!!?

My 12 year old brother thinks that on the Playstation 3 that when you go onto Life with Playstation-Folding @ Home that is shows all the Playstation 3's in the world and the little yellow dots are the playstation 3's. He also says that it is still searching for the Playstation 3's in the world and after a while more yellow dots will show up. BUT! I told him that it is just the cities that are the yellow dots. My brother thinks that when you listen to music and you do the visualizations with the Earth that that Earth is a satellite in space giving you real time imagery of the earth form space! Please give me an answer!
