2009 Gabor Doleviczenyi (Zinnober) realized the facade of RWE substation Herkulesstraße. 2016 innogy / RWE engaged Zinnober to design the facade of substation Alfredstraße at Essen's southside near Grugahalle.
In 2013 I started with a new hobby. In the beginning it was difficult to get reliable information how to find streetart in public space. In 2016, I had the idea of sharing my information with other street art enthusiasts and started my blog “Streetartwalks”. When I found out about this new street art community at the beginning of 2018, I was immediately on board.
