Two videos patched together from multiple AFM frames. The first shows an aggregate of many small, imperfect algorithmic crystals, zooming in from a 25 um to a 25 nm field of view. The second shows a large crystal grown from a nucleating strand, illustrating how the "Sierpinski" pattern degrades with distance from the nucleating boundary as more and more assembly errors are made.
