After 16 years of resting in peace, hip-hop icon Tupac Shakur was resurrected at this year's Coachella Valley Music and Arts Festival with the help of his old friends Dr. Dre and Snoop Dogg -- and a bit of magic from effects powerhouse Digital Domain. The two MCs tapped the creative direction of Chief Creative Officer Ed Ulbrich, along with director Philip Atwell of Geronimo Productions and Dylan Brown of The Yard Entertainment, to bring the rapper back to life for thousands of festival attendees (and another million or so, judging from the online video counts).
