I made a few origami/papercraft models of RGB and Negative RGB for modmad’s webcomic The Property of Hate. And just in time for the update! Both are quite small, about 5.5 cm, not including the antennas.
Model derived from Jo Nakashima’s origami Mario/little boy: https://www.youtube.com/watch?v=r6AzIYGkigM
RGB’s head is a papercraft tv, so sorry for those of you origami purists.
