I think this has been mentioned before, but I was gifted a nice (very bright) flashlight a bit ago, and I realized that by shining it through my hand from the palm, it’s super easy with the naked eye to see my Spark 2 in L2. It’s harder to capture on camera, but I tried:
With the naked eye + some manipulation I can see L0 and R0 implants too, but it’s much darker, and harder to captured on camera.
Just thought I’d share, it’s kinda neat to physically see an implant in a sea of flesh and blood.
