Glas Platz, glass speakers

Sounds been a hot topic in the past few years. Pictured right are "Glas Platz", glass speakers, an elegant solution to those large ugly looking speakers. This technology also works by using the SoundBug, which is a device you slap onto to any hard surface, and whala, that surface projects sounds. Below are a few more sound based inventions I've come across. Enjoy!
