1248 books with one hundred blobs of random size and colour

Every day at 13:37 my server generates a pdf with one hundred blobs of random size and random color. They are all unique. You are free to download them, and print them if you want to. Or you can buy a printed version, which is not free. If you want a signed copy, let me know on Twitter. If you don't want a book or a pdf, you can look at the website instead.
