when the pedal is pressed the lid opens, releasing a ball that travels down a spiral set of xylophone
steps around the bin. each time the ball hits a step, a note is played. the xylophone steps are cut
in increasing lengths so that the note gets lower as the ball travels to the bottom. from 'xylophone bin' by dominic wilcox
