Early Achievements in Big Cubes

Computer Cubes

Michael is consistently ranked among the top in nearly all computer cubes, for example on the Gelatinbrain simulators.[1] Between 2009 and 2010, he hosted 18 Monthly Computer Cube Competition on the Speedsolving Forums.[2]


Michael has created many twisty puzzle simulators. In June 2010, he created the qCube, which provides a unique interface for the cube in which only two sides and the adjacent stickers can be seen.[3] He has since also created the qCubeFloppy and qCubeIllusion.

Michael also created the qqTimer in August, 2009.[4] Since then it has become one of the most popular online timers.
