Is cloaking becoming a reality?

A cloaking technology was recently developed by researchers at Germany's Karlsruhe Institute of Technology, in which they were able to 3-dimensionally cloak a small section of a piece of gold. Though the section that was cloaked was only a mere 0.00004 inch high and 0.0005 inch across, this is a promising start. Tolga Elgin, a researcher, stated that though the current method of cloaking, in which structures of crystals with air in between effectively bend light around them, is a very promising start, it is highly unfeasable to cloak objects that are quite large, as it requieres a vast amount of time to cloak objects. New methods would have to be developed in order to apply cloaking to larger objects quickly and efficiently. Although there were already technologies that bent lightwaves, radiowaves, etc. prior to this, this is the first 3-dimensional cloaking of any object and might be the first step towards actual cloaking devices.
