It is a clever and simple algorithm which allows even pretty slow machines to do an impressive infinite rotating zoom. Today I will talk you through the algorithm and we will do the actual implementation in Turbo C, using VGA 320&#215;200 and 256 colors.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Let&#039;s Code MS DOS 0x1C: The Dweezil Fractal Zoomer\" width=\"840\" height=\"473\" src=\"https:\/\/www.youtube.com\/embed\/aHkXkFARFGg?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Back in 1993 two Finnish demoscene coders by the names of Dweezil and Tsunami came up (probably independently?) with a graphical effect that became known as the infinite fractal zoomer.
