A few months ago, inspired by an AppleTV shaped apple pie and my girlfriends' relentless addiction to baking, we set out on a π pie project. We did the basic design and researched the potential materials and methods to successfully bring this idea to fruition. Unfortunately theory is often not put into practice until deadlines in the mirror are closer than they appear.
So if you care to follow along, let us present you with "The Life of our π" .
Step 1: Mold design
Since π is a Greek letter, there was no point in re-inventing the circle, I just looked at the obvious place for a good Pi, the font menu of my graphics applications.
There are so many nice glyphs for the letter π, but what I needed was one with a generally uniform width. I just typed π in a vector art application and scaled it as big as a legal size sheet of paper could print.
I cut it out, traced it on a piece of styrofoam and used that as my master template.
