I find Yotaro, a robotic baby simulator with an interactive screen for a face quite creepy. The big face is what nightmares are made of. It helps people learn about childcare by portraying a variety of facial expressions, movements and physiological characteristics all natural to babies. It's pretty cool that it reacts to the user through a sophisticated emotion-control system that watches and senses what they are doing and provides an accompanying reaction. It's superior to other training toys as it can even cry real tears!
