This year at Microsoft’s developer conference Build in Seattle, mixed reality, Skype video bots, and the Cortana Skills Kit all made headlines, but the work of a Cortana fanboy is getting a lot of attention far from the convention center halls where thousands of Microsoft developers have gathered.

The hologram was made by a software developer who goes by the moniker Unt1tled.
