Not paintball related - but took a TON of time in AutoCAD to do.
Start off with this picture of a full back tattoo based on a stained glass window from Windwaker.
Stretch, skew, and trace. With the exception of Link's nose and mouth, the entire thing is a single hatch emulating actual stained glass. Could be laser cut out and stay whole.
Buy a cheap used projector on ebay and a chunk of wood. Many hours later with severe writers cramp from the woodburning pen, we arrive at my sister's Christmas present. I cut it out on a bandsaw after (the perimeter, not the pieces), but didn't get a pic of it complete, I'll have to update later with the cut out version.
