Digital Magic 8 Ball

Digital Magic 8 Ball

The Magic 8 Ball is a fun toy that answers yes or no questions in a variety of ways. There are 20 different responses that it can give (10 positive, 5 non-committal, and 5 negative). A different answer is written on each face of a 20 sided die that floats in a blue liquid.

Each time you turn over the 8 ball it randomly displays one of the answers. This can be an amusing way to speculate about life’s many questions, but it lacks versatility. So I decided to augment my Magic 8 Ball with a digital picture keychain. This let me store up to 60 picture responses and I can change them whenever I want. So in this project, I am going to show you how to make a digital picture Magic 8 Ball.

Beginning of a String

Beginning of a String

Although there have been two different Math Mondays touching just tangentially on the wonderful world of string art, it has never covered the basics of the area, and it’s high time. (Why is it high time? Hint: in preparation for non-basics to come…) The fundamental idea is that you create one or more series of connection points, regular in some way, and then stretch taut strings between the connections (again, typically in some orderly fashion), producing (hopefully!) an interesting, beautiful, and/or mathematically significant overall pattern.
