Just a quick modification of LuccasBode's Stickman model (not exactly sure how Creative Commons works so you may or may not need to credit both me and him with any derivatives of this), with one crucial modification: the limbs and torso have been made so narrow that they only show up as lines under freestyle. Not a lot of work on my part but I feel the effect is still cool enough to be worth sharing.
Something I forgot to mention: I put a noise modifier on freestyle's lines to make it look pencily(yes, that weird jittering is intentional).
