Here's an art video/photography project by Laurin Döpfner who used an industrial sander to grind down objects to reveal the hidden layers. The video is created by about 100 different photos. I love that not only can colours and textures be revealed by this process but sometimes tiny cavernous spaces. I am always suprised by these objects as they leave the real world of solid objects as though being slowly absorbed into invisibility. The reversing is an interesting choice by the artist as it seems to push the video further away from the world of documenting the destruction of the object. Instead I get a sense of taking a peek at the inside of an object for a moment before it closes to my view once again.
