The wallpaper of this week is an abstract illustration by Sebastián Murra Ramirez, also known as MU, a graphic and motion designer from Colombia, but based in Barcelona who has a very inspiring set of abstract illustrations in his portfolio. I’m a graphic & motion designer from Cartagena de Indias, Colombia based in Barcelona (Catalonia), Spain. I believe the power of color and shape can build a better tomorrow for all of us through the ideas these two elements can communicate.
