It's a Sierpinski Triangle! I once wrote a program to draw one of these on a 4.77Mhz PC. It took about 5 minutes to fill in the 720x348 screen.#4: Edith Clark (eclark) on Jul 19, 2011
Must be made by a math major or at least someone with a lot of math hours.#5: Gator (gator) on Jul 19, 2011 [SPOILER]
Joe - I wrote one on my TI-8x (can't remember but I think it was 81 or 82). It was actually a really short program as the calculator already had all these graphing functions to use.#6: Joe (infrapinklizzard) on Jul 20, 2011
Those didn't show up until I was out of school for several years - and were horribly expensive for what they were. I would've loved one to play with, but I'd spent all my money on the computer. Relative to income, that was probably the most expensive toy I've ever bought.#7: BlackCat (BlackCat) on Jan 15, 2018
If I remember correctly, my program was pretty short, but the real numbers involved was what slowed it down. Basically, I used the method I wrote in Iteration #4 (written in pascal).

I thought, for a minuscule puzzle, it was clever.#9: David Bouldin (dbouldin) on May 9, 2020
Joe and Gator reminded me of a story....#10: Gator (gator) on Sep 22, 2020
I started teaching myself BASIC starting in 3rd grade on a Commodore PET. One day I was showing my dad some programs I had written and he set a challenge for us both. He said, "let's see who can make it draw the nicest spiral in the shortest time." He started scribbling on paper to figure out the trig equations he was going to use and i (not knowing trig) set out to solve it with math i did know. About 45 minutes later I said I was done, he was surprised but showed me his spiral. By that time he had gotten it to make one arcing rotation returning near the starting point (0 degrees) a short distance further from the origin. I set mine to go and he watched, smiling and shaking his head as the whole screen slowly filled from the center out with a consistent, tight, SQUARE spiral. He started being a lot more careful closing loopholes in challenges after that!
LOL. Great story David. :)
