1. New Shadertoy visualization
   

   I've added a port of topfs2's shadertoy visualisation (http://forum.kodi.tv/showthread.php?tid=204991)
   
   ... and it's pretty simple to try others from the shadertoy website.

Love it! (yeah, it's been a while since I've updated )
Just how does one add/try others? Can it be done without compiling?

I love the following stuff in case you are still looking for improving the list:

• https://www.shadertoy.com/view/4dl3zn
  
• https://www.shadertoy.com/view/4dBSRK
  
• https://www.shadertoy.com/view/Xd2GR3
  
• https://www.shadertoy.com/view/lss3Df

All the rainbow coloured and those playing with the current background are just...ugly
