Papercraft is cool. Giant, human-sized papercraft, on the other hand, gives me the heebie-jeebies. That said, DeviantArt member Tankball has crafted two eerily realistic papercraft recreations of Mass Effect 3 characters EDI and Jack.
More than just paper though, EDI is accentuated with blue LEDs and Jack's model sports authentic human hair. Tankball estimates that EDI, made primarily from cardstock, cost around $150-$200 to complete.
