This concept keyboard plays on our love of, or at least interest in, marketing by replacing all the letters with logos of corporations whose name begins with said letter. I seriously just spent five minutes picking them all out.
The idea is that brands are so recognisable that we can exchange them with letters, probably the most recognisable symbols we know. It works, too, if you give it a second, although some of them are tricky (The Rolling Stones is only a corporation in the most cynical of senses). It doesn't actually exist, but it's a fun little experiment. [Ignacio Pilotto via Crunchgear]
