Autosomal DNA Inheritance Illustrated

Kitty Cooper's DNA Mapper is a much appreciated utility within the genetic genealogy community. Using the Chromosome Mapper to make a four generation inheritance picture, Kitty's recent blog post, shows a real case of chromosome painting by someone fortunate enough to have DNA test results from four grandparents.
It's easy to see which from each of the granddaughter's chromosome pair came from the paternal and which from the maternal side. Also whole chromosomes at 7 and 21 come intact from different great-grandparents.
Wouldn't it be nice if our chromosomes naturally came coloured like this!
