It's called LISA and I didn't know it existed until now! And it's free (for up to 1300 nodes)!
This can help you design music instruments by telling you the resonant frequencies of instrument-shaped wooden housings like guitar bodies, cigar boxes, etc.!

Berklee and hack/reduce will cohost this first-of-a-kind event March
28-29, 2014, creating a space for hackers to develop tools for music
therapists to use in a variety of therapeutic and healthcare settings.
Sponsors will help shape the Berklee Music Therapy Hack and provide
tools and resources for developers. Practicing music therapists and
music therapy students will present the developers with problems to be
solved in real-life settings.
