Once again, LEGO fans prove their mettle in fantastic ways: David Frank has put together a LEGO version of the classic toy Castle Grayskull from Masters of the Universe. It’s delightfully chunky-looking and captures the spirit of the original perfectly. It has all the internals as well, and is leaving me wondering how he accomplished some of those details. Great job with hiding the studs, too! Take a look at some more images of the castle below the jump, and then try not to pull out that bin of LEGO bricks you have stashed in the attic.
