Graphics design, 2 images

Would like to have 2 images: 1. 'Infinite bridge' - something like here - [login to view URL] (see 2nd image, 20th sec) The image would be used in a creative psychology presentation to symbolize 'transition to a new mind state'. Improvisations with the material of the bridge are welcome, especially if reflections and shadows turn out well visually (ex: [login to view URL] - see second image from top). Design of the sideline can be altered as long as it looks futuristic. The overall shape of the bridge must preserve that periodic wave line perspective. Fuzzy decorations avoided. The bridge has to be suspended over ocean with a reclined surface (ex: [login to view URL], at 2.05 sec., but without the planet and more transparent water color). 2. Simple drawing 3 D coordinates, XYZ -style. The vertical line, to the right horizontal, and the 3rd directed at 7 o'clock. For back ground, some deep blue color, can be with varied intensity, say lighter downwards. Any draft sketches from past or similar work are welcome for discussion.
