Like the original Nintendo Nunchuck, the FunChuk offers an eight-way analog stick, built-in motion-sensing accelerometers, and dual buttons.
Beyond these, the FunChuk is shaped quite differently. It's more petite and features a bean-like profile. While it's hard to judge its ergonomics from the above picture, we do believe the original Nintendo offering is somewhat superior in terms of build and finish. It's listed on Logic3's Web site as upcoming at $20.
