The truth is that I really liked the contest promoted by @juliank, beyond the incentive I like the fact that it activates the creative, and because it is so complete and varied that it impels you to reinvent and compete with yourself to be able to stay current.
I almost forgot to mention, this is the Simón Bolivar School Ship of the Navy of Venezuela, it serves as a cruise and internships for the future Officers in their Cadet years.
