Student Labor in Painting an accent wall?

Saw this wicked cool pattern on a wall at a local restraunt.  My classroom is too plain. It would be awesome to get this type of embellishment at school.  Maybe if each student did one, we could get an accent wall done?  Not sure yet...

Jazzing up the art room

 easier said than done.  I'm spray painting the legs of my stools bright colors. Start by spraying white, let it dry, then spray a bright color.  Alone (plus a toddler) it took me 2 1/2 hours to finish 10 of 30.  I am tired.  I need to let art club help me finish.  Then somethign fun for the tops?  Acrylic painting of master art works?  What do you think internet?
