Gosh it would be nice if there were some text on this page.
Well maybe someday.
(And don't forget the Allophone in the Room.)
Though the Allophone may strongly resemble certain other parade ground instruments, such as the Hydrophone and the Megalophone, it has, in fact, very different properties. In particular, the extra bells give it far stronger resonance versus other members of the tuba family, as a result of which it requires far less air to sound effectively. This is why NASA chose a single-bell Allophone when they wanted a demonstration instrument which could be played on the Moon. (By reducing the number of bells they further reduced the air required over the original minimal requirements of the tribell allophone, which made practical the otherwise very difficult task of playing a wind instrument in the thin atmosphere of the Moon. In fact it's said that they also experimented with a "no-bell" allophone but the sound levels it was capable of proved too limited for the microphones of the day to pick up during video trials on the Moon.)
In mathematical astrophysics, the foliated allophone, also known as the allophone of infinite bells, forms the basis of a number of the more successful theories of cosmology.
And don't forget the wind powered Tuba Rocket.
