//1 BIT SYMPHONY
I figured it'd be best if I just quote the text about this project directly from the project's site as it might get tricky to explain since i'm the most non technical person out there:P
here goes: (quoted from http://www.1bitsymphony.com/ )
Tristan Perich's 1-Bit Symphony  is an electronic composition in five movements on a single microchip.  Though housed in a CD jewel case like his first circuit album (1-Bit Music 2004-05), 1-Bit Symphony  is not a recording in the traditional sense; it literally "performs"  its music live when turned on. A complete electronic circuit—programmed  by the artist and assembled by hand—plays the music through a headphone  jack mounted into the case itself. The project is set to be released on Cantaloupe Music on August 24, 2010.
While 1-Bit Symphony is purely electronic in its execution, its  contents reflect Perich's long-standing interest in orchestral  composition. Since the release of 1-Bit Music in 2006, Perich's  compositional work has combined 1-bit audio with acoustic classical  instruments, providing insight into the conceptual and aesthetic  relationships between physical and electronic sound. With 1-Bit Symphony,  Perich brings this insight back into the digital realm, juxtaposing the  grand form of a classical symphony with the minimal nature of 1-bit  circuitry.
