This video is a great example of what you can achieve if you are talented and have to much time on your hands. The group behind the video have found an empty parking garage where they have positioned bottles in a row with just the right amount of spacing between the bottles to play the Super Mario theme.
To play the theme they fitted a RC car with a metal rod and then they drove along the row of bottles and the result is a RC car playing the Super Mario theme.
I know this might sound simple but it must have taken a lot of time to get the distance between the bottles right and driving in a straight line is not as easy as it looks.
