It's called Battle of the Geeks, and the premise is that in each show two crack teams of inventors/engineers (a.k.a. "geeks") compete to perform a different task in a different part of the world. This show takes place in the second largest canyon in the world: the Fish River Canyon in Namibia. Each team was given an egg
and their task was to get it as close as possible to a target on the other side of the canyon, about a kilometer away with a vertical drop of 200m. Without breaking it. The target in the photo is the red-and-purple X on the left. It's 10 meters across, which should help give you a sense of scale.
You can find a much more detailed description, with better photos, from my friend Jeff's account of being on the show.
