If you think the Wiimote feels good with its reactive vibrations and sounds, then you will be amazed with the Novint Falcon game controller. Albeit, you probably wont burn as much calories or give your roommate a nice swollen black-eye, but you will definitely experience the most realistic interactivity that lets you feel weight, shape, texture, dimension, 3D motion, and force effects.
Once again, I couldn't resist myself but to give it a try. The rep let me try a simple demo by virtually feeling around a ball of molasses, a ball of ice, a ball with textured ridges, and a ball of sand. Not that I normally like feeling balls, but I have to say I really enjoyed this. I could feel the viscosity of the molasses, the slippery surface of the ice, and the roughness of the ridges and sand with such realism.
