Crochet for the Classroom: 'Teacher's Gallon Friend'

Sometimes my son brings home school assignments that strike me as crochet-worthy. Maybe it's my imagination, but doesn't this look like a crochet design waiting to happen?
 
The body is a gallon and the arms and legs are the four quarts. They each have 2 pints, and each pint has two cups (or "fingers"). 

Surely this diagram would also help metric-using visitors to the United States who are confused by our strange logic of pints and quarts :-)

Here's what I worked out, and uploaded the downloadable pattern PDF today to my pattern shop at DesigningVashti and in Ravelry:

My son wanted to keep the original prototype (red at the center). We presented the new yellow-centered one it to his third grade teacher, Mrs. Karen Newhall. 
It now hangs at the front of her classroom.
