An excercise designed for the CGCookie course: Mesh Modeling Fundamentals. In this course, you are taught the basics of modeling different meshes in blender, and better, simpler ways to do otherwise tedious and repetitive tasks. The challenge for this excercise was to modify 3 primitives (in my case, a cube, cone, and icosphere) using only the techniques taught in the course thus far. So as much as I would have like to make a tank and whatnot, keeping it simple is good. Like I said, as this is an exercise, it isn't my best work, nor will it be the best I upload here.
