iPhone App Fun - Newton's Cradle
Newton's Cradle - enabled
I came across Newton's Cradle in the Appstore the other day, and at the sight of seeing it, it brought back memories, so I downloaded it immediately.
I use to have one long ago, and for some reason, I fell in love with watching it, and seeing the different patterns I could get the swinging balls to bounce against each other.
Now modernize in form of an iPhone app, this popular executive desk toy is loads of fun.
