The_jetboy is taking the concept of a “seed part”* to a whole new level. He’s used a single piece, the wide track link, 92 times to create this crazy microscale citadel. It’s not often I find visually interesting models made of only one part type.
*A seed part is single part type that must be used in a model, ideally in a highly ingenious manner. “Seed Part” contests are a staple among fan sites. If you’re not as crazy as the_jetboy, you also use other parts in conjunction with the seed part.
