You may have noticed that all of the screenshots displayed on the home page are for BW/grayscale calculators. I would like to add several newer screenshots of programs for color calculators, such as the TI-84+CE or the Nspire CX.
The programs must be written in TI-Basic or hybrid basic (i.e. not solely assembly or C). If you know of a particularly worthy program, please nominate it in this thread, and explain why you think this is a good example of the skills fostered at TI-Basic Developer.
