Grrr. I hate it when I make a deep philosophical entry and immediately follow it with something trivial. But I had to mention this - what other major than computer science would have something that sounds as cool as "mach bands"? Aww jeah. Mach bands.
The definition: "Bands of color that are not smoothly blended across a 3-D primitive."
Aww jeah. Mach bands :)
I'm gonna be snickering about that one for a while. Clearly I need sleep.
