You might not be able to have conversations or go into combat with this papercraft version of Jack made by tankball, but you've gotta admit, it's pretty freakin' cool.
I mean, geeze, look at how tall this thing is!
Although it makes for a slightly creepy picture, this Jack comes apart too. It's for easy fixing.
This Jack -- which, if you'll notice, even has hair -- took about four months to complete with Paint. Yeah, Paint!
