Another two titles that share similar psychological themes, ideas about reality, existence, soul, identity and humanity and its' connection to modern society relationships and technology. Looks like Key is the predecessor to all anime that raise spiritual queries.
Oh, and you can see how some scenes from Key (for example the doll creating scenes in the OP) were used in GitS too.
