For a few days the Kossuth tér (Kossuth square) became green in front of the Parliament building. Those green poles are actually speakers. Special new technology from the U.S. which is exhibited first time in Europe. You can hear music or sound of river, birds etc. from the speakers but only if you step onto the narrow pathways. They introduced it as revolutionary technology for the future concerts and public events but to be honest I didnt find it as a big deal:)

Budapest seems to be full of wierd and wacky avant garde things! I definitely plan to visit
I like this, the whole idea of bring the sounds of the countryside into the city’s it a big plus. I would love to have seen this and walked those pathways.
I think they try to make people aware again of “natures sounds” and to start learning to listen also to the small and beautiful things in life. Maybe something what people in big cities are no more aible to do and have to re-learn it again! I think it’s a wonderful idea!
Thanks for commenting on my blog, Zsolt! Nagyon szepen koeszoenoem!
I’m with you… light coming on when you clap seems to be more sophisticated to me…
