Original Sound Track is a simple but wonderful concept by Ricardo Seola: a combination of a wooden toy train and a music box. The metal keys on the train are plucked by the pins on the track.
The tracks can be put together in different ways, creating different arrangements of the same song. This will teach children about music and composition. The idea is to have more songs available so combining them would also be possible.
I think it is a great idea to combine toys with music in an original and educative way (not that plastic crap with noisy sound chips inside). For this train the question is: will it work?
