Dan, at the last dinner (which you missed) :) derek pointed out that any marking is pointless cause you don't know from which angle the robot is reading the mark. at a simple "T" a read stripe means turn left.... BUT if the robot reads that (...) (21 years ago, 25-Aug-03, to lugnet.org.ca.rtltoronto)

My markers are _after_ the T, and they just tell you if you're going (...) (21 years ago, 25-Aug-03, to lugnet.org.ca.rtltoronto)

The original thought was that before each joint there would be 1 strip or 2 1 strip means 'go left' (as left as left can be in a 3 d grid), or 2 stripes means go right (again, same). As pointed out, however, which way's left or (...) (21 years ago, 25-Aug-03, to lugnet.org.ca.rtltoronto)
