Rig is a user interface design tool with development in its early phases. Rig takes its cues from the gaming industry, moving application designers into a new realm of responsiveness and design conventions, expanding their app design creativity. The current UI design model has been relatively unchanged for decades: a designer uses a powerful desktop system to create an experience targeted at a phone or tablet or another client with very different screen sizes or capabilities. Rig provides real feedback cues to the designer based on the targeted device.
