I had to give blood at a doctor appointment the other day. My veins are tiny & pale & everyone but extremely experienced phlebotomists usually winces when they see what they have to work with. This time, the doctor used a vein finder flashlight to look beneath the surface of my skin. It's creepy as hell! THAT's what's cavorting under my skin?! I immediately came up with another million-dollar scheme: a vein finder that would lock a needle automatically into a good vein. The doc said no, you have to feel for it, there's no way to make it automatic.
