Virtual Reality is definitely a big buzzword for gaming lately with project Morpheus and the Oculus rift. Greater immersion into the game is becoming a bigger deal. Now a new kickstarter campaign looks to add a new dimension to VR gaming, by adding wind!
The fan supports Unreal Engine and Unity and if successful will likely expand to other engines. It might not be the ultimate gadget but it definitely makes the gaming experience a whole lot more real.
For those who have issues with motion sickness while playing VR games, using a fan is often a way to help. This will surely be a double win.
