Fanboys (and girls) with enough cashflow and skill can certainly drop a few jaws with their heartfelt creations / collections, and while the Mac cathedral certainly holds a special place in the hearts of Apple freaks abroad, the Nintendo playhouse doesn't fare too badly either. While the production certainly isn't perfect from an architectural viewpoint, the creativity and sheer brilliance of such a domicile is worthy of applause, as the life-sized Game Boy, littering of characters, and barrage of retro inspirations are enough to make just about anyone show some respect. Unfortunately, we've absolutely no idea where in the world this palace is located, but until the quest to locate it finally concludes, be sure and hit the read link for homegrown Nintendo mania.
UPDATE: We've been informed that this was a part of the spring carnival at Carnegie Mellon University, and we owe this honor to Sigma Phi Epsilon, who had the hand in constructing it. Kudos!
