Here’s an interesting concept for electronic devices called “Used as Read”. The devices are in the shapes of the words that they are (yeah that was an awkward sentence but I’d rather just write this little blurb than go back and try to figure out a more eloquent way of saying that). So the radio spells out the word radio, the speakers spell out speakers, etc.
Obviously there might be some logistic issues in creating these, particularly with the speakers and subwoofers as their sound is particularly shape dependent. I could see these being a favorite of high end designers that favor decorating in all white- something I don’t understand- color is awesome, use it guys!
