This material is a tutorial for drawing constitutional isomers. It's novelty lies in the ability of a student to listen to the strokes of the pencil on their paper and draw all constitutional isomers of a given compound by doing so.
This certainly is a new approach to drawing isomers. I do, however, believe it will only really be effective and comprehensive when used to draw alkanes, and alkanes only. Any form of substitution or the presence of multiple bonds will likely lead to confustion. The scope of organic chemistry is quie large and unsubstituted alkane chains are not usually a huge focus in most classes. It is, however, a fool-proof method to know how many carbons one has drawn. That being said, the student could always just count them as well.
