Originally designed for a computer music class, the invisible violin was used to perform a simple violin piece written for a theory class.
The wiimote/bioglove capabilities shown in this video only demonstrate a small portion of its actual use. The program I designed is in Max/MSP. The invisible violin, using the same program, has configurations for piano and drum set. Additionally, by running instruments through the sampling program, the number of instrument sounds is in the thousands.
