About 6 years ago Oskar van Deventer premiered his World Record 17 x 17 x 17 cube at the New York Puzzle Party. I was one of the 'expert witnesses' who wrote a letter to the officials at Guiness to confirm that this was indeed the largest n x n x n Rubik's Cube.
Nathan Wilson has shattered that record. See for yourself:

Michael Hostetler They were actually very careful to make the distinction between yours and theirs. "This is a truly amazing and unique kinematic mechanism that functions as a Rubik's cube," said Noel Perkins, the Donald T. Greenwood Collegiate Professor of Mechanical Engineering and adviser to the students, in a news release. "There is no other human-manipulable cube like this, to the best of our knowledge. That said, it is not technically the largest cube. We're aware of a larger cube that requires the user to literally roll it on the ground to solve and rotate the faces. None of that is required by our stationary design. So to be very precise, it is the world's largest stationary, human manipulable Rubik's cube." https://www.google.com/.../giant_rubiks_cube_installed_on...
