Rubik's Cube

I am grateful for the Rubik's Cube. I learned how to solve it a few years ago, but it's the simple "seven-step" method that can be learned online with time and practice. They are fun to handle with your fingers, and it's a lot of fun to solve a mixed-up cube in front of friends and watch them be impressed. I don't consider myself a master "cuber" because I don't attempt to solve a Rubik's Cube in under a minute or something like that. For me, this is a little random diversion that takes a few minutes of my time every so often. I am glad Rubik's cubes exist.
