So awhile back I got hired as an intern to prototype a cheap bird scaring laser system. (I know best job ever) But after doing a couple random builds (spirograph type stuff) my boss has asked me to start designing the actual product and I'm still pretty new to this whole laser thing. Basically what I want to do is have four 532nm lasers going out horizontally in all four directions after bouncing off fan diffraction grating mirrors. I just need a way to get up and down and left to right movement of the pattern.
