>> I assume you don't know about the nail-polish with glitter based protection? >Nope, can you explain? You take clear, semi-liquid glue that hardens. The glue has various colored Mylar flexes (aka glitter) floating in it. Slather it onto a device (we did it for exposed ports on devices). The glue is semi-liquid so it will flow reasonably. Once the glue hardens, the orientation, distribution, coloring and such of the flex are set. Take picture(s) of the hardened glue. (just search for glitter glue) Reproducing the complexity of the glue plus glitter is very hard. Possible attacks is attempting to remove it, and inserting it back in. The right glitter glue is quite brittle so hard to remove it. Heating it will make it hazy before pliable, and cooling it makes them even more brittle. Breaks show up as while surface inclusion in the glue.
