Estonia is a small European country bordering the Baltic Sea. Both its language and culture bear a resemblance to its neighboring country, Finland. But that doesn't mean its pavilion at the Shanghai World Expo is short of distinction and novelty.

Estonia Pavilion invites you to let your voice be heard on urbanization-related topics. Large and colorful piggy banks are dotted around the pavilion. But what are these cute critters doing here?

Toomas Tiivel, commissioner general of Estonia Pavilion, said, "We had a contest soliciting the best concept for the design of Estonia Pavilion. The idea of 'Saving For Tomorrow' finally won out. We like it as a befitting interpretation for the theme of this year's expo."

On the back of each of these piggy banks, there is a topic concerning the urban development. Visitors are encouraged to think about these topics, write down their opinions and put them into the banks.

According to the pavilion staff, clean water protection, an improved healthcare system, and more equitable wealth distribution are among the topics of most concern.
