Beyoncé, the Queen of Epic 3D Projection Performance

Yesterday was World Humanitarian Day and Beyoncé gave a moving performance of the song "I was here" at the United Nations General Assembly. There's no doubt Beyoncé is an extremely talented singer, and when her powerful voice is complemented by floor-to-ceiling 3D projection, the experience is ridiculously captivating. This isn't the first time Queen B has made a statement both socially/politically and visually--she performed her debut single "Run the World (Girls)" off her album 4 at the 2011 Billboard Music Awards, which again left people speechless. I'm surprised more artist/performers don't utilize 3D projection, but then again, the standards have been set pretty high.
