I don’t know about you but I would love to get my hands on a holographic version of Amazon Alexa. As it turns out, if you know your coding, you can build your own. Jarem Archer has built such a device. His Holographic Cortana appliance is powered by a Windows 10 device with 4GB of RAM and Arduino for the platform lights. It has 3D printed components too.

The developer used an omnidirectional microphone on top of the unit and a mini speaker unit on the base. The software consists of a Unity 3D app that animates Cortana and a proxy service that parses data communication to/from the Cortana web service.
