Apple seems to be onto something new of late. They've been exploring the implementation of the smart port into future hardware. It will eliminate the current printed port icons that are on hardware today, such as for Firewire or Thunderbolt in favor of introducing "invisible-like" icons that are created by using micro-perforation techniques. The reason for doing this serves two purposes. The first is to once again refine Apple's hardware aesthetics and the second is to add the ability to introduce active or morphing port icons. These new morphing icons would be able to communicate both the location of a port and/or any danger associated with it.
