Well, now that more news has come out about the development of materials that may be able to render people and other three-dimensional objects invisible, I figure it's time to get excited. Now we can definitely wander around Hogwarts after dark without being spotted by Argus Filch. Or, for the grown up kids, you can potentially sneak into the girls' locker room. Just beware that these real-life cloaks probably don't work so well in such foggy conditions.
Maybe it won't be too long before science also gives us other once-thought-imaginary movie gadgets, such as the portable memory erasers from Men in Black and Men in Black II. Looking back at an old Cinematical Seven on the subject of such gadgets, it's interesting to note that the photo enhancer of Blade Runner seems to have foreshadowed Photoshop, the computer from Minority Report is now closer than we had thought thanks to touchscreen computers and even a form of the Nike sneakers from Back to the Future Part II was recently released.
