PaVG #23: Invisibility

Usually, when someone asks what superpower you would want, some say invisibility. It may be possible in the future to achieve this, however. 

The idea behind cloaking, as many seem to point out in the comments of the video, is fairly simple: bending light around an object such that you are unable to see it. In my opinion, Team Fortress 2 does this very well. The Spy class has an invisibility watch that allows him to cloak himself for brief amounts of time. However, if the spy comes in contact with an enemy or takes damage, his cloak will "blink" and an outline of his body will become visible. This makes some sense, as the cloaking device in the video requires careful calibration of the lenses in order to cloak an object, bumping into the spy might mess up his cloaking and cause him to blink.

My only question is do you think this will ever be practical? Given the precision of the instruments involved, if anything moved, the entire illusion would fail. What I'm wondering is if something like the Metal Gear Solid cloaking suit would ever be possible.
