Or at least while it lasts. A pair going by Scott and Mike are well on their way to creating a playable voxel-based The Legend of Zelda in honour of the game's 30th anniversary. Hosted at Zelda30Tribute.com (via Nintendo Life), the fan recreation is built entirely in WebGL, mixing 3D voxels with the music, sound effects and basic ideas that Nintendo tends to protect fiercely. Maybe they will make an exception in this case, and the Zelda tribute will live long enough that areas like this no longer exist.
The browser game can be explored via PC or mobile-based web browser using keyboard or on-screen controls. It's not complete, but the beating heart pieces are in place.
