This Portal-themed HoloLens mod is a triumph

Someone has managed to make an augmented reality mod that brings Portal’s titular device – and its iconic companion cube – into the real world via Microsoft’s HoloLens AR headset.

Developed by , this mod allows the person wearing the device to see images of the portal gun, its orange and blue portals, and the companion cube overlaid on top of the actual environment they’re set in. As such, the portals and the cube will interact with the geometry around you.

For example, the cube will actually bounce off stairs or the sidewalk, giving real presence to these illusions that only the person wearing the HoloLens can see or hear.
