Russian company Vito Technology was in one of the booths around the Mobile App Showcase at Macworld 2011 last week, and they kindly sat down to show off new versions of their apps, all coming up in the next month or so as free updates on the App Store. Popular astronomy app Star Walk was first. It's getting a visual enhancement in the next version, with a brand new sky and a new look to the stars that's more visually interesting than the current setup. The other feature that will be added is a "calendar of celestial events," where things like meteor showers or lunar eclipses will be tracked (per your location) so you can see when something interesting is coming
