Rubik's Cube can be moved into many interesting patterns. Here are a few from David Singmaster's classic book 'Notes on Rubik's Magic Cube, Fifth Edition', pages 47-49, published in 1981. After a pattern has formed, you can use the Solve action (default key S) to undo and redo it as often as you like.

<qt>Mathematicians calculate that a 3x3x3 cube can be shuffled into 43,252,003,274,489,856,000 different patterns, yet they conjecture that all positions can be solved in 20 moves or less. The method that can do that (as yet undiscovered) is called God's Algorithm.<br><br>Many longer methods are known. See the two Wikipedia articles on Rubik's Cube and Optimal Solutions for Rubik's Cube.<br><br>Several methods work systematically by building the solution one layer at a time, using sequences of moves that solve a few pieces without disturbing what has already been done. The 'Beginner Solution' demonstrated here uses that approach. Just over 100 moves solve a cube that is shuffled in 20.</qt>
