Major Cubing Projects/Activities

Note: mostly written for experts

Cubefreak (June 2003 - Present)
Personal cubing website. Over 2 million visits since launch in 2003. Contains many widely-read articles and documentations of speedcubing and blindfold cubing methods (selection below).

Original works in speedcubing theory

Advanced F2L (June 2010)
All D-cross F2L cases (pair type, target slot, any empty slot, AUF) solvable by right-handers without reduction by rotation or a wide turn. Includes many previously undocumented algorithms. One of the first attempts at near-exhaustive documentation of F2L. Additionally, a collection of various F2L tricks; named OPF2L and Jeff2L, providing the very first documentations.
M2 Guide for blindfold cubing (August 2008)
Mostly expository documentation of Stefan Pochmann's M2 method for 3x3 blindfold cubing, with an original approach to M-slice edges.
Makisumi-Garron Last Slot (MGLS) (2004)
Alternative approach to substeps of the Fridrich Method (CFOP). Proposed concept and found algorithms in 2004 (algorithms/documentation later improved by Lucas Garron). Inspired more recent adaptations such as MGLS-P and MGLS-ZZ. Adopted in part by 6 out of 16 finalists at US National Championships 2009.

Expository works

A 3-Cycle Guide to 3x3x3 Blindfold Cubing (June 2005, first version)
Documentation of the 3-cycle Orientation Permutation (3OP) method to 3x3 blindfold cubing. The first comprehensive guide aimed at competitive blindfold cubing. Used by several world record holders in blindfold cubing between 2005-2006.

Other documentational works and services
