Recep Tayyip ErdoÄŸan, unable to make the trip to a party meeting in the western Turkish city of Izmir, recorded his message against a green screen.

In Izmir, a full-body hologram of the Prime Minister roughly 10-feet tall appeared from a coil of blue light, waving to the cheering crowd. 

The video below shows how it was done. It's all a bit like something out of the 'Wizard of Oz' but the crowd seem quite excited by it all, cheering and clapping. 

Erdogan is currently under a lot of pressure amid claims of corruption and the resignations of many high-level officials. His hologram appearance was to ask his fans for their continued support.
