What's worse than mashing a Lego brick into the bottom of your foot? Mashing one into your face-parts (I would imagine). But. BUT! If it's as part of a DIY Lego-based VR headset, maybe it's worth it.
The headset above was built by Redditor lordrothschild, who posted about his Google Cardboard-inspired setup over on a subreddit devoted to Oculus. If you're interested in making your own, there are actually plans for a different (iPhone-sized) headset floating around out there.
Sure, cardboard will probably be better when it comes to ease of use. And comfort. But for style? It doesn't get more nerd-cool than this. [Reddit]
