Alright, so looking back on my work with the dragon curve reminds me that I had 16x segments that are 8912x8912 of different parts of the dragon curve. So uh, here's the preview
Here's a google drive link to a 35648x35648 40 iteration dragon curve. As far as I know, this is the largest image of a dragon curve ever rendered. There's actually a little bit of artifacting when zooming in all the way, so this may not be pixel perfect and is probably more along the lines of a 35ish I dont exactly remember. Still the largest dragon curve image I think anyone has ever generated. This was made using my GPU implementation, because a CPU could never dream to render such a high quality image of such a beautiful curve.
Actually here's the zoom, there's no way this is the full 40 iterations
