As soon as someone comes up with a daft idea you can be pretty sure that there'll be another who'll make it real.  In the run up to the iPhone's launch a common joke was the idea of Apple making an iPhone Shuffle - no screen like the compact DAP, just a single button which would dial a random number.  Well, if you've always wanted to make new friends and crank calls, here's the application for you.

Made by Voxifera.com, the webpage seems to pick a random US phone number which is automatically dialled when you hit the big green 'Shuffle' button.  So don't expect to get somebody from your phonebook!
