title: How could I program a spider's walking movements?
body: <p>I'm programming a spider that should have realistic movement. Currently I'm using this site as reference for how the legs should move, but I'm unsure how to implement it.</p>

  <p>I know that some of the points move in a sine wave motion assigned to an x or y value and the ones that rotate around a fixed point are straightforward, but I don't understand how the bottom two 'feet' points move in relation to the other points. I'm not looking for code here so much as an explanation of how this could be turned into code.</p>
  
  <p>Don't hesitate to ask if I haven't been clear enough, thanks. I'm building this in Processing by the way. </p>
