So, here's some footage of me riding my bike one handed around the Arc de Triomphe. Camera in one hand, other hand on the handlebars. Risking my life for your entertainment. Hope you enjoy. And turn down your sound to avoid hearing the nasty wind screech in my mic.
I've ridden down part of the Champs Elysées and crossed Place de la Concorde a number of times, but I have never actually done the Arc de Triomphe on a bike (mostly because there is no need to, due to the secondary ring of streets -- rue de Tilsitt and rue de Presbourg).

Yes, I've thought of various ideas for fixing a camera to my helmet and so far the only solution I have is duct tape. And kudos to you for knowing that such a set-up is called a gimbaled recess. What a 100 dollar word Bixa. More videos to come.
Gimbal mountings aren't particularly useful for that however. What they are good for is normalizing the mounted object relative to the horizon when the frequency of the disturbing motion is substantially lower than the natural frequency of the object mounted in the gimbal system. For higher frequency motions, the control must be active rather than passive and the human head is located by a very sophisticated active mechanical system with a feedback driven closed loop control.

fumobici - Touche! (I've gotta learn how to use French accents on my keyboard). Your conceptual comprehension of the nature of gimbal mountings is commensurate with your ability to explain their purpose in language which the layman can understand.
onlyMark - Aren't you forgetting the Cannonball Run?
Probably a better solution for mounting the camera would be something that would adjust it so that it was aiming where the eyes were pointed, rather than slightly higher, as would automatically be the case with a helmet-mounted camera.

Bixa - I think the only solution to come reasonably close to following the eyes would be to tape it to my temple. Since the eyes can move independently of the head, though, I don't know that it would be possible to have the camera mimic exactly what the eyes were doing.
It should be a snap to mount a helmet-cam that more or less exactly follows where the eyes are pointing (obviously when looking straight ahead). If the camera is aiming too high (or low etc.) just adjust its angle on the helmet.
At first I found riding on Euro cobblestone streets disconcerting and moreso because the bike I use there is an old French city bike without any toeclips or clipless pedals, just rat-trap type pedals. At first it felt like my feet were going to come off the pedals over bumps, but I quickly regained the confidence I had using that type of pedal when I was a kid. Also, at first the fat 650B French-spec tires seemed clunky and slow before I realized when when inflated to only 30 PSI or so they just soaked up the cobbles bounce. Now I love riding that old Peugeot over cobbles.
I know someone that mounted a cam on his motorcycle helmet and broadcasts on his web page as he is touring about via a laptop he has mounted on the bike and the use of his cell phone internet connection. The view isn't bad from up there, but can be a little bumpy for example when he runs over brick streets downtown. I believe he just has it held up there on padding.
Edit to add: Do your loved ones know you are doing this? I have stood atop that Arc and I know what that traffic looks like. I am quite certain a smack or at the very least a very serious application of "the look" is due you for this one.
