You mentioned before that you're pulling inspiration from Syd Mead for the futurism. So I looked through his work and modeled out some shapes that I thought could be useful. He's obviously got some very unique shapes too, but I think these are ones you could use many ways.
Viz Dev artists - If you're doing a 3D rough layout for some of your room or prop ideas, you can go ahead and use these as a starting point if you want. Alter them, duplicate them, whatever. Just so you're not fussing with maya as much. Or throw them down in PS. Just thought it might be useful somehow.
