1. During my last year of high school our trigonometry teacher let us do string art for the county fair

since there were several 4H members in the class. The project that I worked on involved working with three colors of thread to present what looked like a hexagon when looked at in two dimensions. However, when all three dimensions are included then the art could be viewed in three different perspectives: a small cube sitting in a corner, a small cube that is cut out of a larger cube (1/8th of the volume of the larger cube), or a small cube being projected from the larger cube. Our project won a blue ribbon.
