I have now found who came up with the idea for the
school mural of "Grande Jatte" - no wonder I couldn't
remember who posted it... it was ME! I found it on
Arts and Activities web site:

The lesson idea came from Charlotte Skurow
(Cincinnati, Ohio)- and I doubt I even posted her name
when I shared the link before.
