Bob the Beetle lives on a coordinate plane and is currently at facing north (that is, in the positive -direction). Bob moves unit and then turns left. From there, Bob moves units (west) and then turns left. He then moves units (south) and again turns left. Bob continues his progress, increasing his distance each time by unit and always turning left. What is the location of the point which Bob makes the left turn?
