What is so special about writing Pi in base 10? Pi to me is nice and perfect as it is, but gets ugly and un-natural when written as a long row of numbers. Even if your single-sided loop was a nice idea.

An interesting reference to Pi in this photo is out-pf-focus bubbles and the bokeh circles in the background, so I'll give you a five for that part.
