There's only so many basic shapes that actually work, this isn't like sci-fi where we can make interesting swooshy bits that look cool and have it still function.

We're not going to get something that looks like an Eagle from Space: 1999 unless someone figures out a form of propulsion that's not dependent on the rocket equation or aerodynamics, such as pushing directly against the Earth's magnetic field or something.
