Way back in 2010 we wrote about Bricasso, an iOS app for virtual LEGO building on your phone and tablet.
The developer has been hard at work upgrading it in the intervening years and version 2.3 has just been released. I don't have an iOS device to test it on any more but if the screenshots are anything to go by it looks to be excellent.
Find out more at the Apple AppStore. Note that it's a free download but has in-app purchases that unlock enhanced functionality.
