Project Cronauts – Workshop Heriguards

Zagreb, EU


We are a group of virtual passengers named Cronauts. We travel all around the world learning about cultural and natural heritage.

We wish to join your project Carboard Challenge with workshop “Heriguards” (meaning Heritage Guards). We will create little carboard creatures that protect trees. They are “Treeguards” and they are part of a large “Heriguards” family.

The workshop will take place in Public Library Dugave, the Zagreb City Libraries in collaboration with American Corner Zagreb, on October 1, 2016 from 11 a.m. until 1 p.m.

Inviting The World To Play

The Global Cardboard Challenge began in 2012, following the overwhelming success of the short film, 'Caine's Arcade'. In 2017, we hope to surpass 1 million child participants!


Inspired by the short film, ‘Caine’s Arcade,’ the Global Cardboard Challenge is an annual event presented by the Imagination Foundation that celebrates child creativity and the role communities can play in fostering it. This September, kids of all ages are invited to build anything they can dream up using cardboard, recycled materials and imagination. Then on Saturday, October 7th, 2017, a day that commemorates the flash mob that made Caine's day in the short film, communities come together and play!


Here are a few resources to help you host an awesome Cardboard Challenge.
