I've gone arty here and created a short video of marbles moving around a square, hitting the sides as they go. These marbles have a mind of their own.... TURN THE SOUND ON....!
I'm tempted to do another with food, perhaps hazelnuts or dried beans......
The sound is just as important as the moving image as you will find out when you press play (with sound on please).
All done in one take using a Canon 5DMk3, Atomos video recorder and H4n for the sound.
