While computer simulations are limited to what you program in to them, it's not always obvious what result you're going to get when you create a model and implement it. With as few as 3 chemical components you can create complex dynamics including chaos and other non linear behaviors that are not always predictable and rarely intuitive. Having read Dr. Bray's work, he was analyzing the effect of random fluctuations in the model and the model allowed him to figure out the mechanism that allowed a bacteria to adapt to chemical gradients. This would have been very difficult if not impossible if he tried to do this through typical wet lab techniques.
