#179, but im so sorry i cant make the dot of i's to become acoustic hole, its been used by another fellow designer. so i must respect it.
#198,
#199 are new concept, this image still represent of "bend"ed sound wave and an post-modern architecture style, which often playing with organic shape. i can tweak it more for you if you like.
