Bokeh Lens

These Bokeh lens covers can produce some pretty nifty effects in your photographs. Essentially, they appear to turn blurry parts of your picture into the shape of the hole you've cut in the Bokeh. For example, the hearts in the background of this picture of a dog are produced by the custom Bokeh lens. Learn how to make your own Bokeh and then go show off your stuff in the flickr group. [via]
