Solving the Rubik's Cube, Professor Cube, Square 1, and Pyramix Puzzle

For anyone who has tried to solve the Rubik's cube or the Pyramix (Pyramid) and failed, these pages contain easy to follow instructions, including pictures. The instructions apply to both the 3x3x3 and the 2x2x2 cubes, or to the Pyramix. Also available are instructions for solving the 5x5x5 cube (aka the professor cube) and the Square 1.

These instructions only involve a handful of moves and are thus fairly easy to memorize. Once you are proficient with the moves, you will be able to solve a scrambled cube in 3 to 5 minutes. Thus, these are not speed cubing moves. If you wish to learn more about speed cubing, please browse the List of Cube Links or visit

Shakespeare Play Summaries/Synopses

I have made summaries (i.e. synopses) of each of Shakespeare's plays available. These summaries are bare-bones and without commentary; they simply cover the basic plots, though beginning with the 3rd play, they begin to get quite lengthy. I wrote these summaries while watching the BBC productions of all of Shakespeare's plays (on VHS) in the 1990s.

Dart Scorekeeper

The Dart Scorekeeper can be used to help dart (Cricket) players keep track of scoring and game statistics when playing the games of Cricket, 301, or Golf. It supports up to 6 teams of two players each, includes modes for both cut-throat and polite scoring, and ranks players based on a unique algorithm that takes player strengths and recent games played into account. The software includes a graphical representation of the dart board plus the ability to play sounds for each player and important events (customizable). See the distribution page for the installation file.


Computer Case Mod: Window in Hard Drive

I have added a plexiglass window to two hard drives: an old 420 Mb drive and a 40 Gb, 7200 RPM drive IBM drive. I installed the 40 Gb drive at the top of my computer case and added a window in the case to view the drive plus two blue LED's to illuminate it; 30 pictures available. This mod was inspired by Linear1.Org and others including OverClockers.Com
