I've been getting my kids (10 and 6 year old boys) to let me stare deep into their eyes so I can try to figure out the highlights and incredible depth in the human eye. I keep catching myself wondering if I could get some generic person with attractive hair to let me scan it to use as a tex map. Yep, it's definitely yet another addictive thing in my life, but it is getting me to pay attention to people a little more. GrayMare
