If you don't mind looking like a dangerously eccentric maniac, the Jason Roussel 'audioBOMB' is just for you. Don't let its exterior deceive you, though, it does a lot of good on many levels.
Not only is it made out of recycled materials, it amplifies your music in a unique way. Yes, the Jason Roussel 'audioBOMB' is a sound amplifier, not a handmade bomb. Inspired by graffiti, it is a low-cost audio device that works with MP3s. According to The Design Blog, "they are meant to be strategically placed out of sight in order to emphasize the sounds emitted from them."
