An explicit solution of the four dimensional analog of the Rubik cube is posted at: http://www.frontiernet.net/~jmb184/solution.html This page includes extensive graphics which are intended to make the solution clear and visible. Also, during the process of developing a detailed explaination, I realized that by using similar display techniques, a 2D analog of the cube provided an interesting model of cube solutions. This 2 dimensional 3X3 cube simulator is at: http://www.frontiernet.net/~jmb184/3x3cube.html All of these are written in Javascript, which means they do not require extended interaction with the server to manipulate. They are read in directly and then can be kept for running off-line. John Bailey
