Croatian team organized an Evening of Mathematics in its school (The Evening of Mathematics is official project of Croatian Mathematic Society that gathers all sorts of educational institutions that are willing to support this project).
The students collected and planned tasks and assisted visitors in solving the same. They also organized workshops, one of which was the workshop of the Golden Ratio in which students measured how "perfect" visitors were.
Here is a movie about our Math Evening:
