I've seen a few projected laser image systems, most of them pretty small, but here's one that seems similar to the majority.

I may be missing something. I can see how he goes from left to right, how does he go up and down ?
and you might want to see

...10 to 45Watt lasers......(from internal link)
...and Bragg cell modulators...not a DIY project - high voltages and high power, class IV lasers.

                           I don't quite see it            01/01/70 00:00      
                              At least two alternatives            01/01/70 00:00

                                                                                             I wouldn't be surprised if Chico has a working projector            01/01/70 00:00      
                                                                                 Where ?            01/01/70 00:00

                                                   Probably better than average, unless small angle            01/01/70 00:00      
                                                      In order to have high speed, you must have low mass            01/01/70 00:00
