Eight years ago the Berlin Philharmonic used a similar series for ads. Here is their cello (((it’s actually an upright bass – thanks for letting me know in the comments, Charles Brooks))). (more about that series).
This is also a very nice series of photos inside instruments.
Do you think you would enjoy living in rooms that are not square? I was wondering about that when we built a studio for me in 1994. None of the three rooms was square, none had a flat ceiling. I spent a lot of time in those rooms and can honestly say that I prefer rooms that are not square. If I should ever get to design a house for myself, which is very very unlikely, I would make rooms that are A) not square and B) have some rounded walls and corners.
