Hello, I made an experiment with the first 1000 billion digits of Pi, http://plouffe.fr/piat1000billion/ each image is 10000x10000 and there are 10000 images. Each digits -> gray scale image -> colorized result. The choice of colors is simple ; random. The combined image size is 1000 billion pixels. I could only put the first 220 billion digits on the page because of space. I am working now on finding a site for the rest of the images. caution : the page is huge, 10000 thumbnails. Best regards. Simon Plouffe
