O. A simple letter with subtle variations. It's amazing the amount of ways you can create a circle. Each typeface has it's own character and it's own O, and yet it presents the least opportunity for change or originality of all the letter forms. The one above is the geomtric Neutra, with a strike through the middle, keeping with the geometric theme...

I have created hundreds if not thousands of 'O' variations during my years working at Oakley. Many Os were sketched, rendered and sketched again. Maybe I will post some of those variations for my next design quota. Is that cheating? It's good to be king...
