The poster?


What does the poster represent? Is this a microwave or a sound wave?

BUMP!! I came here to ask the same question. The logo / symbol / poster. My wife says its a picture of two canine teeth.

there is a kind of waveshape called "sawtooth". It is more or less triangular.
Maybe there is a waveshape called "dogtooth", and its shape is like the one in the poster.
I've never heard about a wave called "dogtooth" though. On the other side, "sawtooth" is very common

'sawtooth' is also the name given to the triangular style roof structure that you see at the father's factory
