I do the same thing as Retta, and each year try to touch on the artists that
the tables are named for, as well. As a culminating activity last year, I
gave each table a basket of goodies on "their" artist (postcards, books,
magazines) and they each had to design a pair of sunglasses in the style of
one of "their" artist, or one of the artists "in the room".
It was interesting when Roy Lichtenstein passed away last year,,,, (I let the
"Lichtenstein" table line up first,,,,, verrrry quietly. It is funny to note
that the students get rather attached to "their' artist during the year. Of
course, they're all different for next year!
