Resolution Independence
It's not just for icons. :)
There is some talk of resolution-independence these days, and for good reason. Them pixels is getting smaller.
Those of us who like to cheat and use 2D impostors for 3D objects get to be a little more careful these days as well. Luckily, thanks largely to information I got at the Big Nerd Ranch OpenGL class, one can easily make the 3D equivalent of vector graphics in something like (say) maya or wings3D and wrap them up in a display list in openGL for speed of rendering.
This makes one's visualization happily zoomable and resolution-independent without much of a performance hit. Just load your model in your initialization and wrap the drawing in a display list.

and zoomed waaaaay in:
Can you tell which part of the graph is still a stretched image + simple texture?
