Technology That Allows Users to See Through Walls and Melt Objects

do you think that this kind of technology does exists as we seen in movies? as we know. in movies they used special effect! 

i found this article at http://www.infoniac.com/hi-tech/latest-invention-technology-that-allows-users-to-see-through-walls-and-melt-objects.html 

here today. researchers from the University of South Australia in collaboration with Nokia started working on one of their latest inventions that would make it possible for users of cell phones to see through walls! haha.

imagine if this technology is released? what do you think? it is a good thing or vice versa?

it would be interesting to note that the researchers have also been working on an invention that would make it possible for users to see and sense virtual objects!
