Extraordinary Square Bokeh

For those of you who know about Bokeh (click to find out more) this should be pretty amazing to see. Bokeh (background and foreground blur) is usually the shape of the formation that the shutter blades make when the camera is triggered. The size of the Bokeh is a result of the focal length within a lens.
With my costum Bokeh presets - (see earlier post) - I can force the Bokeh into different shapes. Here I've chosen a square, which shapewise is directly opposit of the usual circular Bokeh - furthermore a square is not cheesy like other costum Bokehs such as hearts, smilies or other rediculous inventions.
Anyway - click the photo above and pay attention to the blur in the background. That is freaking fancy!

Also here is a sunset taken with my square Bokeh preset.
I just want to point out that these two photos have undertaken no manipulative process. It is purely analogue effects.
