Make sure you download the art file and use your framing tool, both layers are on one sheet.  Make sure you set your laser to CUT mode for whatever you use to create this project.  (maybe xTool will actually start giving me points for my contributions).  I would upload some video, but the site doesn't have a location to upload MOV files from an iPhone.  I will have a YouTube link very soon with the entire process.

After pulling all cut parts out of the sheet of which I've made very simple. 

• Decide how you want your layout to look, place one behind the other and give it your own creative touch.
• I added spacers between my layers to give it a little more 3D effect. I also put a spacer behind the back layer.
• To do the spacer, just use pieces you pulled out that are smaller than the wood you are using for your art (make sure your support spacers are not visible from the front).
• On mine there are 4 layers (including the spacers), so I put 3 small scrap pieces behind the right-side front piece of art to support it. 
• on the second layer of art I put, one scarp piece behind it and one scrap piece in front of it to stand off the front and back.
• I cut an extra rectangle to paint blue to go in my junk shadow box (see picture).
• An FYI, use your extra parts not only for spacers but use them to support your art while you are gluing your spacers in. This will keep your art flat, so you don't have an odd, warped look (this is probably the best advice I could give anyone that is looking to get into 3D layered Art Designing).
• I will update with a video link once the new video is done.
