im probably gonna steal that designThe bat is glued onto clear plastic and that is then glued onto the chest piece so when you look at it the bat is floating in the middle. The lighting I used for the test was just one of those little LED disks that you stand glass ornaments on. I am going to try a few different methods to see what lights up best but mainly I will just make a box behind the whole bat symbol and line it with reflective tape ( or in my case kitchen foil) and put a few LEDs inside and then that should give enough light to light the all around the floating bat.
