“Speiragraphs produce mathematical roulette curves of the variety technically known as hypotrochoids and epitrochoids”.
This tool generates speiragraphic-like images, similar to the images produced by a popular and well known toy with a similar name. The longer you leave the generation, the more complex the pattern will be, don’t leave it too long though, or the image will become black with too many lines. Hit the refresh button to generate a new image.
When you’re happy with the image, hit the “s” key on your keyboard to save it to your computer. Once you’ve done that, hit the refresh button to generate a new unique image or let the image evolve more and hit the s key again.
The image will be generated complete with a semi-random file name. There’s a small chance that a file name will be repeated. Just change it manually or use your own file naming conventions. It’s up to you.
Disclaimer: There are millions of possible permutations of images based on many random variables coded into the software. It’s unlikely that there will ever be two images exactly alike, but there will possibly be some that look fairly similar.
Details:
Image size: 2400px width x 3000px height
Resolution: 72dpi
Design: Randomly generated speiragraphic type images on a transparent background.
Notes:
Because there’s a transparent background, you can post-edit these images to apply any sort of background color and add effects such as drop shadow with your favorite image editing software.
For Amazon KDP you will need to post process the images to increase the resolution to 300dpi. You can do that in photoshop or other image editing software. Personally, I use “FastStone Photo Resizer”, just google it. It’s completely free and free of malware, adware etc and you can batch edit hundreds of images in one go! (Changing the dpi won’t affect the quality of the images).
