My favorite exhibit was Pasadena (TX) Memorial High School’s “Alternative Energy Digital Pipe Organ.” This was a full-size instrument (three keyboards and two octaves of pedals) with the sound of a pipe organ that was built by students at the school. I had a chance to talk with Matt Koby (the chief engineer) who is a senior this year and Mr. Alexander Graham (the physics teacher). We were treated to a concert by organist John Potter, another student who was involved in the project who is now a music major in college. The organ is kept in the physics lab at the school—I want to teach there! For more information, click here for the project website. The project was funded by a Toyota TAPESTRY Grant.
