Just when I start to get bored with my iPod touch, a new app comes along that makes it like new again. The app in this case is Solar Walk from VITO. I have reviewed the amazing Star Walk previously here (a celestial viewing app), but was wondering when they would get round to adding 3-D planet exploration to the mix. There's a great (and free) PC app out there that does this called Celestia, and Google Earth also has some pretty awesome planet/star-gazing features.
