For my workforce development class, I show how a sorting algorithm works using NeoPixels (red larger, blue smaller).

A common starting point for learning about algorithms (and their complexity - big O notation) is sorting algorithms. It dawned on my that a NeoPixel strip could be used to visually show the numbers of a Bubble Sort floating to the top. And, that this visualization could then be compared against other algorithms, such as the Quick Sort.”
