Well wouldn't it be nice to have you're own pool? And if you don't live near the beach having you're own pool sure would be pleasant. Summers is still going strong here and the weather is pretty good for a swim. Found this picture of a swimming pool with the same shape as an acoustic guitar. Why not? Sure looks alot better than a plain hole in the ground. There are actually many swimming pools in the world that do have strange shapes. You can find them around turist locations, hotels and such.
But there is something with the shape of a guitar that really works well when it comes to swimming pools though. If you look close there are even some guitar strings along with the soundhole painted on the bottom of the pool. And the placement of the stair going down at the fretboard looks great.
