Today is National Inventor's Day, in honor of Thomas Edison, and Giz is going to celebrate it with some designs from the Work In Progress show by students at London's Royal College of Art. There are no less than four concept radios in the show, including this one by Mikael Silvanto, which melds a slide rule with an iPod-esque analog radio. The other three, including one which uses QR codes to hook up graffiti artists with pirate radio stations, are below.

Yuri Suzuki's design uses a Post-It pad to mark out the frequencies of pirate radio stations that caught her ear while living in North London. "My radio enables you to make notes about the radio station and mark its position," she says. "The radio looks like a memo pad, but underneath is a speaker; the pencil acts as the antenna that controls tuning and volume."

Yuri feels there is a connection between graffiti artists and pirate radio stations, as both are art forms that hack into public spaces. Her Future Pirate Radio lets you tune into pirate radio via QR codes. First, the graffiti artist stencils a QR code onto the wall, incorporating it into their work. Anyone who takes a picture of the graffiti will then be able to tune into the pirate radio station that inspired the artist via the internet.

Finally, Jochem Faudet's work consists of a pair of radios whose controls are grouped together in order to make it easier to use. Actually, it's rather complicated, so here's Jochem's own explanation:

"Radio 1: All the tuning and volume functions are grouped around the speaker. The On/Off switch and volume function is situated closest to the speaker. The AM/FM switch is situated at the end of the tuning circle, by flicking the switch down it points to the FM numbers situated on the outside of the circle or by flicking the switch up it points to AM numbers on the inside of the tuning semi-circle.

"Radio 2: The tuning function and volume function are separated from each other in this concept. To adjust the volume one has to turn the wheel with the integrated speaker, by sliding the AM/FM switch to FM it hides the frequencies of the AM and vice versa."
