Buy speed Rubik's Cubes here- http://tonyfisherpuzzles.net/PuzzleShopSpeedcubes.html I guess this is more of a puzzle transformation than a true replica since it uses a Rubik's Cube as the core instead of a custom built spider like Erno's original. It's a little too brown and shiny because the wood dyes and varnishes I used weren't quite right to achieve the desired finish.
