Some amazing CNC artworks

We don't have chance to use CNC machine to make our own artwork in this quarter.
These are some good examples of CNC artworks.

Moreover, I really love this artwork of shoes by using CNC machine.

 "This shoe is named after a deadly octopus from the Pacific Ocean (Hapalochlaena Lunulata) that has large bright blue rings on its mantle. The intricate perforations for the upper were laser-cut and she then coloured the edges by hand. The wooden heel structures also resemble the texture of the octopus skin and have been made using a CNC milling machine. Due to their complex structure each heel took between 7 and 14 days to make!"
