The bumf says, "A two-day course centered on experimenting and iteratively fine-tuning urban designs with Fablab. Use materials such as frames and stencil sheets in combination with light and mirrors in order to create spatial constructs." Hmmm, Spatial constructs, you say? Isn't that another way of saying anything at all? Lights and mirrors, but no smoke? Most peculiar. Read a bit further in however, and it does sound jolly interesting, so if you're in travelling distance to Amsterdam in mid January, and you've got 150€ spare, it might be a fun couple of days.
