It is large colorful poster representing 20 illustrated birds. The free augmented-reality app allows to listen to the birdsongs. You can listen and listen to the songs as many times as you want, then challenge yourself by playing the Memory, which includes different levels of progressive difficulty. The project was funded through an Europeana grant and a crowdfunding campaign (nov 2018). 

The poster is now avalaible for sale in the e-shop.
