Melinda Green writes "Readers who enjoyed the previous Slashdot postings regarding the 4-dimensional Rubik's cube called MagicCube4D will be interested to know that a couple of brilliant developers have recently created a working 5-dimensional Rubik's cube. Operating a 5 dimensional puzzle projected all the way down to a 2D computer screen may seem a hopeless task but the full 5D puzzle has already been solved by 3 people. Also noteworthy is the fact that the 4D puzzle has now been ported to Java and is available as both a full-featured desktop application and as an Applet."
