I recently came across all-interesting.com and stumbled upon an interesting article about hologram technology. Holograms have been around for ages, but nothing much has come of it except for a few cool looking stickers and shiny seals on shiny products. It seems in the past few years holographic technology has taken giant leaps forward and could possibly be responsible for the end of captive animals and traditional zoos. The technology in question is known as 7D hologram, and it's pretty epic as to what is possible. The mix of next generation computer graphics and projecting those images into a 3D environment is the next form of entertainment and something that is being used in Dubai and Asia as an attraction. The holograms are so realistic you literally get the same experience as you would when looking at animals in zoos. For example, when you go to the zoo you are usually at a safe distance from the animal or behind a protective barrier. You can see the animal, but you can't touch the animal, and you probably wouldn't want to get too close to a lion etc when you think about it. With the aid of this 7D technology, companies have written software that project the animals you'd normally see at the zoo, and actually it's a bit more of a show! Most animals in zoos have no interest in interacting with humans and sometimes seeing a miserable lion pace up and down is not exactly great viewing. Animal rights protesters have been pushing for zoos to be closed for many years now, and with this new technology starting to take off it might not be too long before you see a digital zoo experience pooping up in a city near you.

Really interesting article. I think it would be much more beneficial to let more animals be free rather than locked up in a cage most of the time, so having this technology on board would be a sight to see!
