Welcome to Junior Hackathon

Junior Hackathon, a feast combining code and culture, will take place at Helsinki City Museum on April 22 at 11 am to 5 pm. At the event museums, companies and NGOs turn cultural heritage into digital creations. Old pictures, treasures from sound archives, or familiar passages from TV are tinkered, scratched, remixed and mashed up by kids of 7 to 15 years.

Join the full-day hackathon by signing up beforehand or pop in while passing by. Take a granny or pal along!

The event is organized by Open Knowledge Finland / AvoinGLAM ja it is supported by the Ministry of Education and Culture.
