Gee, Tom, I know very well what I would do from those, and I'm not joking at all like the others
.
Take the first pic you took, see what that shape suggest you, what could come out from that shape with minor additions or modifications.
Forget about tables, cabinets and other pieces of furniture, that shape is already a start of something really striking.
Explore your mind and the material potential as itself, because once you cut it and square it it will be like any other wood board. Do work hard on the ideas and on the design, and please, please do not be eager to start cutting it, use that initial shape to create something that is already there.
Put the boards upside down, capsized, perpendicular, inclined and see beyond the material.
I know it sounds very mistic but please think a lot before putting a saw on those boards.
