The rather tasty little iPhone application FontShuffle has just hit town, courtesy of the folks at FontShop.

The app lets you browse through a selection of Font categories (sans serif, serif, slab serif, script, blackletter and display), and then to pick from a list of relevant sub-categories (so serif would take you to grotesque, humanist, geometric, gothic, decorative and hybrid), and then to a list of six of FontShop's available faces. Then, and this is oddly fun*, if you want to see a further six faces, you give the iPhone (or iTouch) a shake, and a new set pop up.

Select one of the typefaces and you'll get The Quick Brown Fox text in that face, swivel the screen to the landscape mode and you'll get the glyph chart.

This is the first version of the app, and at the moment it's just a friendly little marketing tool for FontShop, without any hugely practical uses. But they're promising to add more faces, and more functionality, so it could go somewhere very interesting.

Cheers to Caspian for the heads up.
