Crowd Surf Racing

2 opposing players must Crowd-Surf over a group (or 2 separate groups) of people whilst maintaining the relatively steady balance of an electronic device that measures current rotation (like an iPhone). Think Egg-and-Spoon race whilst crowd surfing.
If the player drops their "egg" (i.e. allows their electronic device go off balance), they lose. First one to the end of the crowd wins.

Players must pace themselves and coordinate with the crowd carrying them in order to be victorious.

Here are some informative diagrams.

[Figure 1.0] This is the general layout of the game

Much like any race, this game contains a start/finish line, once a player reaches the finish without losing the balance of the device, they win.

[Figure 1.1] How the device will work

If the player loses balance of the device, an alarm will sound signaling their lose of the race.

Upon reaching the end of the crowd, the player must place the device on the ground or a flat surface, this will tell the device that it is stationary and no longer in use. The device will then sound a Winner Alarm!

And that is my game idea.
