What to do, what to do? Have a party!
I went out and bought art materials and some big plastic tarps and invited all my friends over. "Hey folks, it's kindergarten time!"
I promised everyone that any completed artwork would hang on my walls for a year, and the stuff that was created was so wonderful I kept it all up for two and a half years!
The next summer, I again provided art materials, and invited people over to make fish. I then hung these fish from the ceiling of my bedroom. It was wonderful: it was like waking up in an aquarium. :-)
(I would have kept them up longer, but I ran off to graduate school and couldn't really take them all along.)
