title: Old school tv edge-warping effect?
body: <p>I am trying to achieve an old school tv effect. But I'm having trouble finding a good way to warp the edges of the screen, an effect you can see in this example.</p>

  <p>I'm not asking anything about getting a glitchy, or static effect. Just the warping around the edges of the screen. I know this is definitely not possible with just plain css. Would this be possible in webGL or html5 Canvas?</p>
