My original idea of this assignment was to use the random walk to create a filter, but that didn't work well (at least it didn't look as well as I expected). I gazed at the dots of random walk for a long time, thinking about what I could make based on it, then I got inspired by Tinker Bell.
I use circles and vertex to create the light spots; canvas will get brighter and brighter based on the random walk of sandy areas. Also, the light spots will change colors based on their location.
I realize that the effect of my sketch can learn because the light-spots always go back to where they have been. But I still want to figure out how to implement the self-avoiding walk.
