A poster can speak, would you believe it? Recently the notice boards of Liverpool UK covered with amazing posters which can playback music. This poster is about a musical show. There are some thumbnail images placed in the poster and if someone touches it, it will play a music. Also this poster allows you to book your seat to the musical show. There's an another thumbnail button and when pressed it will play back your seat number.
This new poster is the next generation of the posters. These posters can placed like other posters on notice boards. This poster called as "Listening Post" . This poster made in the normal paper with a printed circuit.

Listening Post is really like a normal poster but it made out from a conductive paint. All the parts including graphics, letters of this poster is also a part of this circuit. Solar power used as the energy source for this poster and used solar powered batteries. These batteries also printed on the poster which is unnoticeable. The speaker of this poster also printed on the poster (There is a special technique used to thick the poster, then a speaker can easily place).  If the speaker volume too low then there's a headphone jack also.

There are some ongoing experiments to reduce the cost of this poster and also researching the ways to increase interaction this with people. One technique already added is the  "Like" button. People can vote the "Like"  and which will store in the circuit. Later, those votes can be counted.
