It's possible?!!! Of course NOT. And that wasn't a hologram. It was made by the Pepper's Ghost technique and it was CGI. Technology really did came a long way in a short time, but not long enough. 'Simple' holograms and even teleporters do exist but we'll have to wait at least 15-20 years. Soon, we will have quantum computers and holograms like those in Star Trek, but not at this time. And they spent at least 300 000 dollars to create realistic CGI Tupac and to do the things you said with the Chipmunks with todays technology would count in millions. But it would be great.
