The 
Tomi  Ungerer Museum asked me to create a science-fiction illustration workshop 
        for the 2014 Heritage Days, on the theme 
Strasbourg Cathedral in 3014. 
        In the museum, I gave every visitor a printed paper on which he could draw 
        how he imagined the cathedral in the future. Then, he sticked his « brick » 
        on the wall next to the others' to make it part of a huge collaborative picture. 
        
         
        I conceived the printed base bricks so that they can link to any other brick by any edge.
