Puma have released an iPhone app that brings a little joy to the credit crunch and is set to be a nice little viral gem.

The PUMA Index is a real stock market ticker with a difference. Each market has a different model associated with it and when the market goes down their clothes start to come off, and if it gets really bad they strip down to their Puma branded undies. Aswell as bringing a little cheeky fun to your day you can get 20% discount at PUMA stores when you show the app.

The free app only follows the DOW at the moment, so for our local blog readers we will have to wait until the afternoon to see any action as the models are currently asleep. Also don't worry that you will be bored inbetween market activity as you can see from the video below that the models will be kept busy. And what would happen if things got really bad? Well according to Antonio Bertone, PUMA's cheif marketing officer, they'll start having pillow fights if the market crashes.

PUMA will be releasing the German (DAX) and Australian (ASX) markets soon along with a web version of the app for all non iPhone users. The only problem is you might not want the market to rise as they will start to put their clothes back on.
