I've never had a dead spot before. It's a weird thing. I mean, it's a dead spot, it's not like I can feel it, pretty much by definition. Still, I can see some opportunity for creativity here.
What should Jay do with the dead spot on his belly?
Get an eight color tattoo of a mandala
Have a bezoar implanted
Wire it for sound
Install a tiny OLED display which can be configured via wireless (the Teletubby option)
Something else I'll explain in comments
