I stumbled across this app for iPhone which may appeal to those favoring the many-worlds interpretation of QM: http://aerfish.com/UniverseSplitter/index.html I thought it was cool that an app can actually run a quantum experiment each time you use it. I saw mention of it on a Sean Carroll blog defending EQM. While it may or may not split the universe, it would seem to allow you to make a completely random decision. And I can't think of many examples where quantum effects can noticeably influence daily life. Makes me wish I had an iPhone but unfortunately I have Android.
