To use the trunk represents the unlimited possibility of creativity. Just like Mary Poppins' bag, our trunk has everything we need. We just have to reach in and be willing to play with the objects that come out. The play begins when the trunk is opened - the delight is what will come out of it .
The theater clown is also a very old tradition. It is a reflection of our simplest and most innocent selfs. Clowns are able to look at the world with a child-like wonder and feel very deeply the emotions of sorrow, joy, loneliness, and injustice.
Artists I have collaborated with (who have websites): These are some pretty talented people. I highly recommend that you collaborate with them too.
