We will discover the city. Playing devices can be found anywhere. Why are pavement slabs laid out like playing fields? Climb wall projections blind or play a special bowling match in slanted entrance ways. We will explore the city with chalk, soft balls and other little tools, and discover the city as playing space for us, our children and youth and for all those, who might not be able to imagine this. Afterwards you can challenge your best pal on the internet for a round of Spi-El. And where was that biggest puddle of the city district again?
