Coolous was thinking outside the box when it designed these Alien cases for the iPhone 4 that have an alien-like back design that may or may not have strong inspiration taken from Alienware, the guys behind those powerful gaming PCs. Actually, that was the first thing that came to mind when I saw these cases. Coolous' Alien cases feature a hybrid design made up from an external, hard colored polycarbonate shell for impact protection coupled with a flexible, TPU inner layer for shock absorption. The Alien cases are expected to sell for $35. Paul would really appreciate these.
