We have made a second version of our most popular piece, with music by Dimitri Shostakovich (Suite for Variety Orchestra, No. 7, Waltz 2). In this version, the hue has been shifted to change the original colors. the movie is displayed in negative tone to convey a night effect, and it includes subtitles explaining the science behind the device so that it can be used for displays, as well as a little bit of personal history on Shostakovich who suffered political harassment (he was never imprisoned). The device is essentially a microfluidic equalizer. Each of the 7 microvalves (bottom of the image) opens when the music volume exceeds a set threshold in a given band of frequency assigned to that microvalve. The script that converts the music into on/off signal for the microvalves is written in LabView. The microvalves open microchannels containing dye. Flanking the microvalves is a constant background flow of colorless water, which keeps the dyed fluids focused in separate streams. Due to a microfabrication defect, the microvalves leak fluid even when closed, but that produces a pleasant artistic effect. (Note that this suite is erroneously identified also as the "Jazz Suite No.2" because it was first performed in London in 1988 under the title "Suite for Jazz Orchestra No. 2", and Decca published an album in 1991 called "The Jazz album" with excerpts of this suite.).
