BARCELONA, Spain – Mobile World Congress 2010 has been home to a host of exciting Nokia related announcements (get all our coverage here). Yet away from the bright lights of the stage and press conferences there were some lesser-spotted treats, including demos of smart-looking games headed to Nokia N900 via the Ovi Store. Phil has been filming from the frontline to bring you video of these new software nuggets in action, including a giddy new demo for the 3D Rollercoaster Rush game for N900, along with a brain-bending 3D puzzle game called Zen Bound that sees you stroking the screen in an attempt to wrap rope around objects floating in space… yes, it’s very strange, yet super intriguing and utterly original. Also, we take a quick look at the new Firefox app that has been built for N900. Click through and hit play to catch our exclusive video from the show floor.
