Sistine Chapel Ceiling in cross stitch

I like doing counted cross stitch and I've done a couple of big projects, but I don't know that I'd dare start something as big as this.

The complete project is 40 inches x 80 inches or 564 stitches by 1,114 stitches which translates to 14 stitches per inch or 196 inches per square inch and gives a total of 628,296 stitches in total. According the information from the designer it was completed 3,023 days after the initial stitch was made and took around 2,872 hours of stitching, this is on top of the 800 plus hours creating the pattern.

I have to say I am pretty impressed with the dedication and perseverance and I'm tempted to buy the book of the pattern, just to get more of the details of this fantastic piece of needlework.
