Work from left to right, top to bottom. Use a different random number for each early adopter. If there are 3 early adopters in a given cell, use three different random numbers in entering the results in Figure 10. The enthusiast might wish also to animate the entire movement pattern of the grid. First frame contains actual distribution of adopters after two years.
Second frame contains simulated distribution of adopters after two years.
The reader might enjoy using the second and third columns of random numbers to create more simulations and compare them to the first simulation and the actual distribution. From a visual standpoint, one might further imagine subtracting cells from one another and then animating the results. Models that can be simply executed have fine potential for actually being used in real-world settings. References Arlinghaus, Sandra L. 1985.
