Henrique Oliveira "paints" in three dimensions with plywood, as he describes it in a short interview with Museum of Contemporary Art Cleveland. The video focuses on a 2012 work in progress, Carambóxido, which is made from, and still smells like, industrial debris found in the Flats and along the Cuyahoga River in Cleveland. The artist, who hails from São Paulo, is most recognized for his large installation pieces that burst through gallery walls and coil around pillars, appearing to grow from the spaces around them. You can see many more of his paintings, sculptures and installations at Oliveira's own website, which requires flash to navigate.
The Jealous Curator is 'a collection of art that inspires & depresses' its proprietor, who has been updating the site almost daily since February 2009 with series of paintings, sculpture and mixed media, furniture, and always with light-hearted commentary about what's posted.
Daniel Eatock is a London-based designer known for his conceptual approach to solving traditional client problems as well as those of his own choosing.
