Albrecht Niekamp: it´s just sand
I did check it with DOSBox and FractInt. Yes it is noisy with no anti-aliasing. If you make a large image with the disk function and resample it smaller with an image processing program like Photoshop you should be able to get an image similar to the one I posted. The image I posted was generated at 10x10 anti-aliasing so you would need to start with a very large image. You can also just zoom in to make the image less noisy.
david: "Also, don't use Imgur to host image libraries you link to from elsewhere, content for your website, advertising, avatars, or anything else that turns us into your content delivery network."
I wasn't aware of those terms of service. It is interesting though that there are buttons to click to copy the kind of link you want. There is a button for Image Link (imgur web page with your image centered in it), Direct Link (the one I posted with just the .jpg image), Markdown Link (for posting on reddit), HTML (for embedding an image on a webpage), BBCode (for posting on message boards and forums), and Linked BBCode(for message boards). All but the first button seem to conflict with their own terms of service. When I read posts on Reddit I always see images posted from Imgur. They must not mind too much. The second part about granting them a royalty-free license doesn't surprise me. I have occasionally posted images on Imgur. If you use their website they have the right to show the images to anyone without paying you. That part seems fair to me. -- Mike Frazier www.fracton.org
