There are already many tools that convert any image to pure CSS if you are interested in doing this. As well as using base64 in the img source, and javascript+canvas. I suppose the value in doing this is that maybe an image could go right into an email to someone, or if you are hosting a page on the web somewhere that doesn't have the ability to upload images - but you still want to display one - just use CSS. Otherwise - I'm not sure what this post is telling us. Did he do them by hand? Did he just convert some images using freely available tools? I'm not sure the value here other than to show people that there are other ways to display images in browsers than loading and showing the images themselves.
