DLA is super awesome, but if you're starting from a point, it takes a lot of computation. Or, rather, what we thought of as a lot of computation around 1990. Hoff's version of "Hyphae" is orders of magnitude less computationally demanding.

In a lot of cases, if you're willing to throw a massive amount of computation at a morphogenetic problem, you can get a higher coolness-to-algorithmic-complexity ratio.
