title: Isometric projection in 2d coordinate system
body: <p>What equation is needed to move a point on an isometric plane in a 2d space?</p>
  
  <p>I've looked several places on the tubes. <a href="http://awiki.tomasu.org/index.php?title=Pixelate:Issue_12/Isometric_Projection" rel="noreferrer">Mostly here.</a> and I haven't been able to decipher it. I'm not a math major, unfortunately. </p>
  
  <p>What I need to do is move a point from (0,0) to (1,0) or (0,1) on an isometric plane consisting of 10px blocks. In normal-ville I would just do (x+10, y+0) or (x+0, y+10) to move myself on my 2d plane.</p>
  
  <p>I do most of my work in Core Animation on the iPhone if that gives a better context. </p>
  
  <p>Thank you for your time. </p>
