Viikki-speksi ry is an organization founded on the Viikki campus of the University of Helsinki in 2016, with the primary purpose of producing annual musical theater productions. Speksi is a form of student-produced musical theater in which spectators participate in the play by asking for improvisation. Viewers can shout “omstart!” at the point they want, in which case the scene they just saw is replayed in a different way.
