A while back, I blogged the Japanese A.I.Doll artificial companion.
Turns out the Candy Girl artificial companions are more popular in Japan, selling close to a thousand units a year. They've even got a PC game. Check out this oddly hypnotic video to get a better feel for these dolls. On real and artificial women, cute faces and hot bodies make a killer combo.
Oh, and if you don't feel like committing to a particular design, this shop rents them out.
