Turf Cams
CNN.com: Super Bowl to feature tiny 'Turf Cam'
Fox Sports has planted so-called Turf Cams around Alltel Stadium in Jacksonville, Florida -- including four on the field where the New England Patriots and the Philadelphia Eagles will play Super Bowl XXXIX. Eight more of the Turf Cams aren't in the turf at all -- they'll be mounted at the end zones.
"They're so tiny, they're effectively the size of an eraser on a pencil," says David Hill, chairman of Fox Sports and a driving force behind his network's use of technology during sporting events.

Two of the Turf Cams will be placed around each 20-yard line facing the end zone, and the other two at the three-yard lines where snaps are done for extra points. The cameras will be placed at 45-degree angles prior to the game. Video will be fed to Fox's production truck and, if it's good, they'll put it on the air.
This is Fox; I wouldn't be surprised if they managed to sneak some cameras under the cheerleaders. :) Seriously, this sounds like they could provide some interesting footage.
