Caden's things laid out neatly on a Persian rug, in groups: his records, his magazine, his Polaroid prints, his Canon A-1 with its cap and strap, his Nintendo DSi with its games, and his iPod touch with its EarPods. Click a group to lift it into the air, where each thing floats and can be pushed about; click one to look at it close, double-click one to turn it back and hold it still, and double-click it again to let it float; click away, or press Escape, and they settle back where they lay. Click the magazine to read it, turning its pages by dragging, scrolling or with the arrow keys.
