We’re still waiting for virtual reality headsets to become mainstream. But while the so-called killer app that makes these expensive devices a must-buy is yet to arrive, indie developers have been showing us what’s possible within the VR world - such as bringing a rendering of Valve puzzler Portal to the HTC Vive.

Now, the award-winning game is getting the augmented reality treatment, thanks to Toronto developer Kenny Wang, who has created a Portal proof-of-concept for Microsoft’s HoloLens. He shared his creation on Reddit, and it looks spectacular.

"The project itself was developed in the Unity 3D engine, which is fully supported by the HoloLens," Kenny told The Next Web.

As you can see in the video, the headset turns any environment into part of the game world. It’s just a demo, so there are no puzzles to solve, but the way the companion cube reacts to real-world objects like stairs and the table gives you an idea of augmented reality’s potential when it comes to gaming.

Wang’s developed other demos for the HoloLens, including an AR Pokemon game that uses voice commands.

There’s still no word on when we can expect to see a consumer version of the HoloLens, so anyone desperate to try some of Wang’s creations will have to hand over $3000 for a development kit.

Wang told CNET that the demo took a few weeks “on and off” to create. He’s still looking for a job after recently graduating from college, but he said that Microsoft had shown an interest in his work.
