A cup of steaming hot 'Bokeh' coffee...Bokeh is the way the camera renders out of focus light and is derived from the Chinese word 'Boke' meaning blur. With some fairy lights and abit of careful placing you can produce some funky effects:

This image was shot on a 50mm F1.8 Lens, using available light from a nearby window to act as a keylight on the cup. Simple, yet effective! :)
