the projector suports wifi. Are you familiar with wireless networking at all?? The easiest way to do it would be ad-hoc mode, assuming ps3 supports this. you will have to read through the projector user guide to enter the correct setting to connect wirelessly, read the ps3 user guide to connect wirelessly to the projector. The guide makes it pretty simple but im not going to sit here and re-type the whole thing for you.
