A couple of years ago, I explored the Seven Bridges of Konigsberg problem with a set of interactive processing.js applets.. it might be of interest to some here to feel the impossibility of the task, before understanding it with the classic proof:

Thank you for this! loved the interactive puzzles.

Mind boggling how such a basic geometric shape can be impossible to solve using the simple rule (talking about the triangle puzzle in your follow up page)
