To start with, I'm not sure why my rendered image turned out so rough, I tried tweaking several settings and could not get it to render as smooth as the image in my project file. The pink object was made using lathing, just from a simple curved line to suit my fancy. The blueish object I made by playing with boolean compounds, I first subtracted a knot object from a pyramid, then I took the intersection of the resulting pyramid with yet another knot object, subtracting more small shapes from the edges of it to keep it to the three simple geometric shapes that it is now; I was actually able to manipulate it with precision instead of hit and miss, the object is as I intended it to turn out. The green shape was made from extruding many polygons off of a sphere, and extruding more from those to segment the ends so that they could be resized. I then used turboSmooth on the resulting object to round it out. I'm very happy with how the boolean object turned out, and with the lighting effects on the features of the objects, even though I couldn't get a ground shadow from the extruded object to give it more weight. Lighting wasn't quite covered well enough in class, and the book doesn't use omni lights to demonstrate shadows, so I couldn't manipulate the settings for omnis in the same way that the book said to for spot light.
