Added Tube, selected 2 faces and extruded. Duplicated and rotated on a linear setting.
I added spheres to the scene and I lit the scene with a sky, an infinite light and an omni light.
I used one material which was car paint glossy cameleon.
I turned on Ambient Occlusion, Global Illumination and Colour Mapping and rendered at 1680x1080 pixels 72dpi.
I opened the file in Photoshop and adjusted the hue and saturation and also flipped the image.
