Hair tattoo?

 

I don't know what to call it exactly; I don't even know where I got this idea from, to be honest with you.

 

Basically, the thing is to cut hair really short (<5mm)and then make some sort of a pattern or an image similar to tattoos only in this case it's done with hair by cutting/shaving it later upto the skin.

 

I'm looking for an inspiration, a web resource about what I've just described.

 

Can anyone help me out?

 

Thanks in advance ;)
