- It would depend on a few things. For instance, how big is the screen (in
- pixels)? Does it wrap around? Where does the walker initially start?
- (The last question doesn't matter if the screen wraps toroidally.)
-
- More important, perhaps, is: How is movement actually done? Does it
- pick a random direction and walk one space, then pick another and walk
- that space, etc.? What happens if it tries to step on a pixel it already
- has? Nothing, or does it automatically have to pick another direction,
- counting as the same step?
