Autodesk and Dartmouth College have teamed up to develop a new interactive design tool called Printone, which lets users create 3D free-form musical wind instruments.
The team designed 16 free-form wind instruments to play different melodies, including a horse that can play Old McDonald, a bunny that can play Little Peter Rabbit, a snowman that can play Jingle Bells, and a dragon that can play Puff the Magic Dragon.
There are also pigs, stars, what i think is a doughnut and even a giant chicken.
“The sound of a wind instrument is governed by the acoustic resonance as a result of complicated interactions of sound waves and internal geometries of the instrument. Thus, creating an original free-form wind instrument by manual methods is a challenging problem,” explained the creators.

“Our interface provides interactive sound simulation feedback as the user edits, allowing exploration of original wind instrument designs.
“Sound simulation of a three dimensional wind musical instrument is known to be computationally expensive. To overcome this problem, we present a novel fast resonance frequency prediction method based on the boundary element method. Specifically, we formulate the resonance problem as a minimum eigenvalue problem of a nonlinear matrix. Furthermore, we can efficiently compute an approximate resonance frequency using a new technique based on a generalised eigenvalue problem.”
