Let's start at the beginning. I was exploring the internet (as you do), and eventually landed on a site called The Library of Babel. Right now, it contains "all possible pages of 3200 characters, about 104677 books". Looking deeper, I also found The Canvas of Babel, which is "an infinite array of every possible arrangement of pixels".
After The Canvas of Babel, I was thinking it would be cool if the TI-84 Plus CE had a similar program. However, I wanted it to be in order, so it can be smaller and not rely on a PRNG to operate correctly. So I created this program, "The Color of Babel".
With over 32,768 combinations per pixel (but my program goes through 65,536) and 76,800 pixels, the final combinations would be 3276876800 or about 3.589259895016700... × 10346786 combinations, which is a very big number. Even though no one will probably reach it, this program shows every picture that does and will exist on the calculator, including the first response to this post, the next winning lottery numbers, and a graphic explaining the solution to cold fusion.
This is just a small (~630 bytes), silly program, and really for me to learn how to use the LCD. The source code is on Github, so feel free to find and implement any optimizations that I couldn't see.
