I've done a couple of posts in the past about R/C rigs that can carry video or still cameras (here and here). The trouble with many of the possibilities is they are too expensive and/or they are challenging to fly. Well these problem are on there way to being fixed! I just ran across the Parrot Drone, available in September, which is a flying video game and flying quadricopter. It is relatively inexpensive ($299) and easy to fly. You fly the Parrot from a iPod Touch/iPad/iPhone via Wi-Fi. Here is a intro video and here is a Parrot's YouTube channel.
The Parrot drone is designed to be a game in which you dog fight with other drone owners operating on the same Wi-Fi network. However, since it has both a front-facing and a downward-facing streaming cameras on board the first thing that came to mind was this could capture some cool shots of almost anything that would hard to capture in any other way.
This thing obviously not made to carry your DSLR but it's got two built-in cameras so it will be interesting to see what kind of video it can create. An important aspect of this device is that apparently the software that runs on the drone is open source.
