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.
