I've updated the Tunnel Effect to allow selection of render method. Previously the render method was selected automatically based on if the browser supports typed arrays / buffers. By adding this feature, one might compare the performance difference between these methods of rendering within the browser.
What I noticed from doing so, was that since I originally made this demo, back in February 2013, both Chrome and Firefox has improved their implementations for arrays. As of Chrome 31 and Firefox 26, their array implementation are almost identical in speed of the buffer implementation. IE 11 does not support buffers yet, and the demo gives an error message if you try to activate buffers there.
