I saw his work for first time in 2010 in the MACBA, Barcelona. I have to say he is the digital video artist that has had the greatest impact on me.  I remember we were in a conference room with three big vertical screens and when the music and video started it was a surprisingly sensorial experience.  Ryoichi was not on the stage, even when the show finished he didn´t appear.  When everyone had left I walked to the stage, raised my eyes and saw him in the projector room organizing his gear, so I applauded him and he smiled.  Great artist.
