Well, I just received a YouTube contact invitation from Oliver Kray, a young designer from Berlin. I watched a couple of his videos, and I have to say that he's doing an interesting job, a little bit 50's retro for my taste, but quite interesting in terms of the finished result.
Another German wall and façade-designer with extraordinary talent is Philip Gaedke. My first impression was: "Gosh, I'll have to use something like that on my next multisensory room". You know, I've never been a fan of superficial textures or any kind of ornament because most of my teachers were influenced by Loos's point of view: "ornament is a crime". For me, texture should be achieved by the own nature of the materials... but I must admit that good graphic design can do wonders and I really admire those results.ciao
