Animated 3D Geometrical Model

I am in need of an animated 3D geometrical model with a curved surface for a presentation. The model should have basic details, with simple shapes and colors. It does not need to be highly detailed with realistic textures and lighting. Attached are two pdf files, Aether unit graphics and forward backward time. The Aether unit graphics image is what the finished project will look like in part. The forward backward time file shows what I have tried to create but cannot finish. I am looking for an inward spiral for the Aether unit. The animation will illustrate starting at the point between the two spheres, then trace the outer surface of the spheres and their tubular loxodromes, and then when at the antipodes the movement from both poles will spiral down the axis to the beginning point. The colors and general appearance will be as in the Aether unit file.

The model will be used as part of a presentation, and should be optimized for quality visuals and smooth animation. The successful freelancer should have strong experience in 3D modeling and animation, to ensure a visually stunning product.

I am looking for a freelancer who will take the time to understand the project, and be able to deliver a quality product on time. Please contact me with any questions or interest in the project. Thank you in advance!
