Where's That Vein? New Tech Projects a Map over Your Skin

You want to give blood, but you'd rather that the phlebotomist didn't stab you more than absolutely necessary. Now there's a system that can help.

The Australian Red Cross is experimenting with a new technology that detects the locations of donors' veins more effectively than the human eye.The system is an infrared light that senses the hemoglobin in the blood and projects an image of it onto the skin of the donor.

I'm guessing it's more specifically a raven, which as a species can imitate a wide variety of sounds such as speech as well as parrots are known to do. Ravens are in the crow family, though, so calling it a crow is still correct.
