In 2003, Iguapop hosted his first solo exhibition in Barcelona, called Sexo Extra Ordinario Ahora. There, he established a connection with Iguapop, the art gallery that was becoming the centre of the lowbrow and street art scene in Barcelona. In 2003, Hoppek left Berlin for Barcelona, Spain, which at the time attracted street artists from all over the world.
In January 2010 Hoppek created a site-specific mural for the Museum of Contemporary Art in Rome, MACRO Future. Hoppek paints less graffiti in cities nowadays, mainly due to increased police pressure, and focusses on graffiti in rural areas. Between 19 he was featured in several books about street art by the German writer Bernhard van Treeck. Hoppek later moved to Cologne and later to Berlin, where he established contacts to the local graffiti scene. In 19 he started exhibiting his work in cafés, a bank and the university library in the small town of Siegen, where he was living at the time. Hoppek started writing graffiti in 1990, under the name Forty. After being rejected from the Kunstakademie Düsseldorf, Hoppek instead turned to street art. Hoppek studied to be a tracer and successfully escaped the military draft in Germany by dodging the medical examinations. Already at the age of eleven he got his first computer, a Commodore VIC-20, and as teenager he took up photography and videomaking. He grew up in what he describes as a "hippie community", where he tried marijuana before he could walk and frequently skipped school. Boris Hoppek was born in the small village of Kreuztal, Germany, in 1970.
