Probably not exactly what you asked for but one of the few times I fell out of my chair in a colloquium was when Erik Winfrey presented his Sierpinski gaskets grown from DNA.

This was the first paper to experimentally demonstrate the use double-crossover (DX) DNA tiles to implement a 1D cellular automata, namely Sierpinski patterns. Hence, a new type of crystal, called algorithmic crystals were born. Here the error rate was between 1% to 10%. In a subsequent work in collaboration with Erik Winfree, we're trying to reduce the error rate of these types of DNA computation models.
