I liked this CT scan from Jason Hinchee, who’s got a stretched 5/8″ septum tunnel in place. The CT scan was done for some upcoming surgery on his ear, so he was able to keep the septum in place… More images of others after the break.
Above is a moth xray which shows Rubber_Duckie‘s tongue web piercing — and if you look carefully you can also see a tooth gem, a nostril screw, and a tragus piercing. Below is Andrey’s xray (sent in by his friend Golddust) showing a couple tunnels and a tongue bar.
