Seep into the frequency plot and volume of this sound wave chair designed by Matthew Plummer Verandez, chiropractically modeled after a note of his own particular fascination. The artist says he is working on a similarly designed toilet, modeled after a 3D graph of the elusive brown note.

That’s cool. I wonder how comfortable it is. Probably not ~$7000 comfortable.
I think it was modeled on LEGO.
