Apparently the similar design has become reality, but the game pad design concept features slimmer size. If you like it, let’s go on checking.
The wonderful design concept is named Apple iPhone gaming extension, and designed by Alan Li. As we can see from the images, the game pad is actually an iPhone 4 case that consists of two parts that respectively come with a joypad, four fire buttons and external speakers, which allow you to enjoy your favorite iPhone games. Apart from that, its form-fitting design and solid construction make the gaming pad double as a nice iPhone 4 case. After the break, check out the rest images.
Unfortunately, at present it’s just a design concept. If you need an available product, you might like to check iControlPad gamepad case.
