I confess that I am not someone who is fanatical (or even modestly enthusiastic) about apps. This, however, is changing since discovering Solar Walk for my iPod. This interactive app is both fun and educational. One can zoom out to the breadth of the Milky Way (for a sobering awareness of how small we are) or zoom in to a satellite in orbit around our planet or drift over the topography of Mars.
There is an information option for every object on screen and even a menu to select a specific cosmic body natural or man-made.
The app also provides an additional music option if one wishes to hear some soothing tunes while taking a tour of our modest collection of astral bodies, and should you desire an added level of immersion the app gives you the chance to switch to 3-d mode (providing you have the appropriate eye-wear).
Other features on the app includes: movie clips, screen capture, and a true to scale option.Mobile, Technology
