1. Animation

Add (Shift A) a Torus

Enter Edit Mode (Tab) and select the middle horizontal edge loop (Alt+RMB)

Duplicate the loop (shift D) and Separate (P) into a different object

With the new object selected (should look like a circle), scale it 0,8 (S .8) (it should be in the middle of the torus)

Convert it to a curve (alt C -> Curve from Mesh/Text)

Select the camera, and (Shift) the path that you’ve created (the selection order is important, first the camera!)

With both selected make parent (Ctrl+P -> Follow Path)

Position the camera on the path, and on camera view, adjust as you want (you may also want to play with Camera Focal Length to distort the image a bit)

Alt A to visualize your animation. (if you think it is to fast /slow select the path and under object data menu, change the number of frames on Path Animation)

2. Colors

Under Materials Proprieties choose Wire instead of Surface for the torus.

Under Shading, select shadeless

Add a new Texture to your material, it should be Blend instead of Clouds

Under Colors, activate Ramp

Now, add a few color stops and change the colors to whatever you want. (just make sure that your alpha value is 1)

Under Blend, change the progression to Vertical

Under Blend, change the Projection to Tube

3. Compositing

Is very very easy, just like in photoshop, duplicate layer, blur it and add it to the original one, like this

Have a nice trip!
