A way to hide large objects from sight at Rochester university called cloaking

• Previous cloaking methods have been complicated, expensive, and not able to hide objects in three dimensions when viewed at varying angles.
• The system developed at Rochester university uses four lenses,with basic,readily available optics
• This provides three-dimensional, continuously multidirectional cloaking.
• The researchers have cloaked a hand, a face, and a ruler - making each object appear "invisible" while the image behind the hidden object remains in view.
• However this not too expensive says the founders.
