Hey Gozert - the beam goes through thru the splitter and depending on which way the splitter is turned, the beam will also go 90 degrees to the left or right. In a few of these pics the yellow and orange are in the exact same spot on either side of the cube and the 589 50mw drowns out the 593 30mw. But in some of the pics, they are at the right angles and the two different colors are visible.
Pman - I know what you mean. Sometimes I will open up my garage door when setting up in the warmer weather, and my neighbors look in and I am sure wondering what the hell is he up to. I have shown a few people my set ups with the lasers on and they could not believe they were in a garage. Hang up some black curtains and with the lights off it seems like a much bigger space
