In the sandbox game Gmod, some people (sorry, I don't remember names) released Pony ragdolls, but on deviantart somebody gave them NPC AI. (Instead of being flaccid and death alike they now "live") This is an undoctored shot of FlutterShy and Rainbow Dash. When I picked the camera tool to take an screenshot, they seemed to pose for me, AI is very basic at this moment (soon ponies would talk and walk around) but they used all their capabilities to shock me. (I know what AI is and what can and can't do) I got genuinelly creeped and amazed... Fluttershy is genuinelly photogenic (da magiks) but even Dashie looks alive and realistic, in this photo sho looks her friend, but after she looked at me like Fluttershy, I expected she to say something... That my most recent experience with alike living things. Historicaly we cannot forgot Elsie and Bessie, the robot "Tortoises" os Prof. Grey Walter (http://www.cerebromente.org.br/n09/historia/documentos_i.htm) the linkie got some info, but mine is from a book, so not mainstream, so better... The robots depicted a remarkable life like conduct using just elemental electronics, they worked like this: a piece of wood with an axle with two wheels ported the components acting like a boogie ported by a third front wheel, that wheel had both, a 360º degree steering engine and a traction engine powering front wheel, both engines got current from two amplifiers feeded by two photocaptors attatched to the spinning third wheel that acted like a head of sort, and photocaptors acting as eyes. The way the "turtle" was wired made it chase any light source, but when being too near, a failsafe inverted the mechanism as "light avoiding" With that, the turtle was superior to a organic animal, the moth, that burns in a candle flame... Said failsafe mechanism was overriden when voltage was too low, so, the "turtle" could recharge in a set of rails conveniently placed below that light, once voltage recovered, the turtle would self un-dock. The turtles (I told were two) also had a lightbulb over their "heads", this gave some interesting results, both they could interact between them and with a mirror, also their outer shell equipped a bump switch so they'l avoid hitting walls and furniture.
