Hatching a Creative Imagination in a Subterranean Rainbow

I've been working on the final presentation of "Subterranean Rainbow" for Hendrix College in Conway, Arkansas.

"Subterranean Rainbow" was initiated to help solve the design problem of encouraging students and faculty not to cross the state highway  and to use this new pedestrian tunnel.
       But, while I feel it is the role of design to solve problems, it is the role of art to ask questions. So  my interest is to make the passageway that is not just a transition space, but a destination place of creative play, a new place for creative interaction at all hours of the day and night, especially on a college campus.

As part of my "Urban Musical Instrument" series, my interest is to create an icon for Hendrix College and the city of Conway, to create a place that encourages social interaction in public spaces, a truly "open classroom."
