The HoloLens has the ability scan a room to map objects and surfaces, turning the world around you into the terrain of the game. After donning the headset again for the HoloBuilder demo, a gentleman from Microsoft suggests that I look under a nearby coffee table. When I kneel down and peer beneath, a charming little Minecraft castle reveals itself. Shadowspresumably from the table abovecover the castle, and I drop a little redstone torch beside a man on the drawbridge. The area around him fills with light.
I notice a small band of Minecraft zombies lurking nearby, and decide that its time for them to die. Shovel, I say, and the cursor transforms into a digging tool. Before my Microsoft guides can give me further instructions, I click a block beneath one of the zombies, and he disappear through the hole like Ive opened up a trap door beneath him. I laugh. What Im actually supposed to do, however, is switch tools and drop a torch near several blocks of dynamite, setting off a chain reaction and blowing all the zombies to hell. I happily oblige. Shortly after the explosion, a virtual lacuna opens up in the coffee table; when I walk closer and peer downward, I see the zombies tumbling into a sea of lava.
Im enchanted. I want to plop down, sit cross-legged on the floor and play for hours with the secret world that I just discovered, but the time allotted for the HoloBuilder demo is tragically brief. My Microsoft guide directs my attention elsewhere (and with the HoloLens, directing someones attention feels a bit like pointing them to the X on a treasure map). I find three blocks of dynamite affixed to the wall, almost like little curios. Naturally, I blow them up.
As the wall detonates, bats fly out from the breach directly towards my face. The Microsoft reps tell me that the HoloLens has spatial audio, so we can hear holograms even when they are behind us. Which, P.S., is a creepy thing to say.
