title: Simulating a car moving along a track
body: <p>For Operating Systems class I'm going to write a scheduling simulator entitled "Jurrasic Park".</p>
  
  <p>The ultimate goal is for me to have a series of cars following a set path and passengers waiting in line at a set location for those cars to return to so they can be picked up and be taken on the tour. This will be a simple 2d, top-down view of the track and the cars moving along it.</p>
  
  <p>While I can code this easily without having to visually display anything I'm not quite sure what the best way would be to implement a car moving along a fixed track.</p>
  
  <p>To start out, I'm going to simply use OpenGL to draw my cars as rectangles but I'm still a little confused about how to approach updating the car's position and ensuring it is moving along the set path for the simulated theme park.</p>
  
  <p>Should I store vertices of the track in a list and have each call to <code>update()</code> move the cars a step closer to the next vertex?</p>
