Lego build the change competition

[yixin]

Hi,

I remember one of my friend joining a competition of building lego called lego build the change, hosted by lego education. I'm just curious to know if anyone has participated too (it is a worldwide contest, the countries change every year), and we can share our experiences in it.

I was there to watch my friend take part, and that time,the contest was held last year june in singapore.
