Singaporean Yong Jieyu's ceramic paper speakers (actually, they're less speaker than amplifier) are made from clay &mdash one of the best materials for sound amplification thanks to its low sound absorbent coefficiency &mdash and recycled music scores. Place your an earphone inside each "speaker" and voila! your tunes can be heard by all and sundry.

The speakers are just a part of the research project into Noise/Sound that he is doing as part of his Masters degree at the Design Academy in Eindhoven. [Yong Jieyu via Treehugger]
