OK, nice work, good point!
Well, you have to extent the algorithm so that when it hits a dead
end, it doesn't stop, instead it tries the other directions.
Or maybe do it like this: just rush forward until you hit
something. When you do, proceed around it as tightly as possible
until you reach the original position!
BTW maybe the AI people already have a true and tested algorithm
for this problem?
