Hi Guys,
Doing modifier experiments now a days.
Just found something cool, must be shared 
In this tutorial we will be “Creating holes without deleting mesh in blender” + making a never ending video with it 
hope you like it

This was fun, however, the moment I clicked on the depth of field things stopped working and the render was gibberish… so I turned it off and things worked fine. I normally work in Cycles so I am not sure why this happened.
yeah it is still in development but still quite awesome 
I use cycles too but as OpenGL is fast+ with Ambient Occlusion and Depth of field in viewport caught my attention.
So then to follow this, I would turn off cycles?
it can work on both cycles and internal render and not affected by any of them. its just a separate rendering engine (sort of)
