S.C. is dedicated to inspiring young graffiti artists, painters and visually talented people in creating comic art books. Each volume is a summary of the contest/workshop held every three months in a different city of Central Europe; each workshop consists of street writing, comic strip exhibitions and discussions.

The contest itself encourages young people to express their view on a topic (chosen by the Sperm coordinator) which often ties into the global issues of our region. A selection of the works is published in PDF format as the Central European Comic Art Portfolio (CECAP).
