A thoughtful life deserves a Thoughtful Shelf

Definitely speech bubbles! I wasn't far off ... Matt Dennis, creator of The Thoughtful Shelves says:

The design was intended to convey the creation of an idea or conversation and makes for a unique piece of furniture. The bubble shelves create a focal point for the piece and this allows you to show off the ideas and concepts you love most.
