Blueprint 3D: Puzzles for the iPad

Each screen in the Bluepring 3D game is a seemingly random assortment of lines floating in three dimensions. When you rotate the space, you can see how some lines might fit together. Eventually, they snap in place to create a two-dimensional image of a familiar object -- a house, perhaps, or the Eiffel Tower. The 200-plus puzzles here aren't terribly demanding, but they're undeniably satisfying.
