Last week at Mobile World Congress 2011 we were treated to quite the show by a developer/designer for SPB Software. The product he displayed for us was SPB Mobile Shell, a bit of software that'd up until this point only been available for Windows Phone (who clearly did not appreciate it.) What we've got here is a full brand new 3D engine with what they're calling "Natural Interactions," which to us means it's simply intuitive. This is an engine made to replace your current mobile homescreen with a miraculously gorgeous looking set of 3D moving panels, with which widgets can essentially come alive. You know what it reminds us of? Honeycomb.
