According to Oleg Tillbergs, the work is a reference to the artist's work - the installation "Stop No. 1", which was created at the São Paulo Biennial (1994). The artist was inspired by the tragic accident of the famous Formula 1 driver Ayrton Senna da Silva, which occurred during the race at the San Marino Grand Prix. About this period and the exhibition at the Sao Paulo Biennale is the author's story in the short film series "What is so contemporary?" The first version of the name was "Serpentīns", but later the name was changed and became a phonetic pun with the Latvian pronunciation of the driver's name Senna - Siena ( Wall in Latvian language).
