3:00 – 4:00 p.m. (Alex Koss and Dave Auckly): Rubic’s cube and cube slicing introduction

It is nice to have a solved Rubic’s cube to play with to discover useful “moves.”
The problem is that the cube quickly gets scrambled and you might not know how to solve it. One solution is to use a virtual cube where a computer can solve it. Here is a link to a virtual cube:

The separate faces can be turned 1/4 turn by pressing:
R for right
L for left
U for up
D for down
F for front
B for back.

The following URL describes one way to solve a Rubic’s cube:

The person juggles and solves Rubic’s cubes at the same time:
