Once again, I'm in agreement with Greg. Strange that, since I'm from the "humanities," and started off as a graphic artist. Maybe its the years I spent as a paralegal....
Those of you who've read Footfall will realize that there doesn't have to be a trade-off between art and science. I'd love to be able to pilot the Archangel Michael in Orbiter! The Orion's impressive, but I think Michael would kick its butt in every measurable way. And it's grounded in actual science! There's no "willing suspension of disbelief" required behind this ship, and it certainly doesn't require unobtanium or handwavium to function (just a massive supply of nuclear warheads).
An artistic eye (function should have a connection to form) should be an asset to the scientific principles, not an end to itself. At least in terms of science fiction. Notice how "science" proceeds "fiction."
Since this is the Meshes Galore thread, I'm curious, does anyone know of a repository with low-poly human characters that are public domain? I'm not satisfied with my efforts here, and am ready to "borrow" someone else's work.
