How cool is the Berlin Boombox by German illustrator and DJ Axel Pfaender? This flat-packed, DIY sound system kit combines fun nostalgia with sustainable tech. Designed to resemble an old school boombox, the graphic black and white is eye-catching as is or can be colored to fit the user's individual taste. Special limited artist editions are also available, showcasing work by illustrators from around the world, including Jeremyville, Rob Flowers, Golden Green 179, and LouLou & Tummie. Compatible with all smartphones and mp3 players, the tool- and glue-free kit comes with easy to follow instructions. The Berlin Boombox consists of recycled (and recyclable!) cardboard and includes all internal electronics.
