What Do You Do With 3 PS3’s?

Last week I picked a Playstation 3 because I am getting a new TV soon. I wanted to get a Blue-Ray player but being that I am also a gamer I didn’t just want a stand alone Blue-Ray player so I got a PS3. Of course being the geek that I am I wanted to see what all I could do to the PS3 as far as hacks and such like changing out the hard drive. That’s when I came across some videos on YouTube about using 3 PS3’s to ray trace a model in real time. But first if you don’t know what ray tracing is here is some info.
