A web, a tunnel

Came across the work of Chiharu Shiota recently, and was blown away by the power of what she's doing. By positioning everyday objects within a dense web of black threads, she somehow captures the enormity of emotional significance, even pain, that these objects can take on in our lives, and the way that sometimes even the smallest forward motions can become incredibly difficult - creating a tension between the desire to reach the object, and the physical/phsychological difficulty of getting there.

Also interesting, from a recent Guardian article on her:

"When Shiota was nine years old her neighbour's house burned down; the following day the artist saw a charred piano amongst the ruins. This instrument that lost its sound has haunted the artist and inspired various works in which she sets alight to a grand piano, then displays the remains within an installation of black thread."

Pietr Uklanski - Abstract Mosaic of a Sort

I just came across the artist Pietr Uklanski yesterday, these beautiful mixed-media works created from pencil shavings. I don't know if he considers these works mosaic, but they have so many of the fundamental elements: the act of destruction (the breaking of glass or stone or, here, the shaving of the pencil) enabling the act of creation, the smaller pieces coming together to form a whole. I love how delicate the whole thing is. See more of his work at Gallerie Perrotin.
