In the days since, it’s been confirmed that Holo-Pac was “Dr. Dre’s Vision,” and now the good doctor admits that he hopes to see the technology spread. TMZ caught up with Dre in Los Angeles, where he graciously — and enthusiastically — answered questions about the hologram, which has been described as his brainchild. Dre didn’t give any predictions for how popular hologram performances might become, but he did reveal the next step, in terms of technology.
