What is the wooden art called where the picture is made wood shapes

I'm not sure what you mean. Do you have a picture?

Do you mean carved wood art? Or a mosaic made from wood pieces?

sounds like a puzzle

I think you are looking for geometric wood art - https://www.google.com/search?ei=Qg1_WquKNsLojwTXhZPoDA&q=geometric+wood+art&oq=geometri&gs_l=psy-ab.1.0.0i67k1l7j0i20i264k1j0j0i67k1.6676.8761.0.10489.10.7.1.2.2.0.149.678.0j5.5.0..3..0...1c.1.64.psy-ab..2.8.697...35i39k1j0i131i67k1j0i131k1j0i10k1.0.X_ao7mRqqfM

you will need to be a little more explicit with your question

Are you talking about Decopoage?

Decoupage is made with cut paper but it can be put on wood. Puzzles could be made out of wood.
