I liked how some of them would "impale" themselves on the end of a plank, like they couldn't see it if it was pointed along their direction of travel.

  It's probably because they have eight "sensing rays" and plank may be located between them.

    Yeah, I can make them have 16 but it slows things down esp on mobile phones.
