Last week, we showed you an amazing PC gaming setup that involved five HD projectors, an omni-directional treadmill, wireless gun peripheral, ambient lighting and paintball gun. Some people cried "it's a marketing stunt!". Others cried "it's not real!".
Those claiming the former, well, the prominent Battlefield 3 placement makes that a 50/50 call. Those claiming the latter, though, eat your words, because this clip shows how the thing was built, and goes into greater detail explaining how it actually works.
You'll also, if this is your thing, get extended views at a British man howling in pain as he's peppered with paintballs while his motion control system breaks down.
