Study of bokeh

I am experimenting a lot these days in an effort to discover new way of expressions through photography. One of the projects I'm doing is a study of bokeh or background blur. Its a simple project to conceptualise but very difficult to execute in my opinion. Here's how... How to do it? Well, I took my EF 85mm f/1.2 L (Canon's king of bokeh) and my 1D Mark III out in broad daylight and I had to look for scenes where the sun would provide a backlight such as a tree. The trick is to spot places where the sunlight could peek through such as between the leafs. Find a nice foreground subject such as a flower, compose as you would normally but making sure the streams of sunlight can get through and there you have it. If done right, the streams of sunlight will be rendered as circles (or near circles) of varying intensity. I want to find more ways to use bokeh as part of the image. Maybe use street lamps in the background at night. Let me know if you have any other suggestions eh?
