Massive steel labyrinth


Belgian architects Pieterjan Gijs and Arnout Van Vaerenbergh built this phenomenal steel labyrinth in Genk, Belgium at the C-mine arts center located on the site of a former coal mine. The 37.5 square meter maze has a kilometer of corridors.

A series of Boolean transformations create spaces and perspectives that reinterpret the traditional Labyrinth is a sculptural installation that focuses on the experience of space. These Boolean transformations convert the walk through the labyrinth into a sequence of spatial and sculptural experiences.

Shadows from NYC supertowers are a bummer

Some New Yorkers are upset about the shadows cast by the new supertower skyscrapers near Central Park and other public hang-outs. Above, the shadow of One57, an 85-story skyscraper currently under construction, on Central Park. At a community meeting on the issue, the president of Extell Development, the firm behind One57, responded that "the shadows cast by tall, slender buildings, which is what most of the buildings going up are, are very brief — maybe they're 10 minutes in any one place — and cause no negative effect on the flora or fauna of the park." According to City Councilman Corey Johnson, the apartments in the superpowers "are being sold to foreign investors, who have tens, if not hundreds of millions of dollars, who are not making this their primary home." Central Park receives 40 million visitors annually. "New Yorkers Protest Long Shadows Cast By New Skyscrapers" (NPR) Read the rest

How engineers freeze soil to create structurally sound solid walls of earth

In Japan, engineers are attempting to contain radioactive contamination from the Fukushima power plant by freezing the ground around it into "ice walls" that will remain frozen for years. At Nova, Jessica Morrison writes about this weird technique, which has been around for over half a century and is more commonly used as part of massive construction projects with large underground components, including Boston's Big Dig.

Artificial mountain outcrop and picturesque villa added to top of Beijing skyscraper

A privately-built villa, surrounded by imitation rocks, is pictured on the rooftop of a 26-floor residential block in Beijing. Construction on the residence took six years, and the huge dwelling offers 1,000 square meters of living space. Residents in the building complained about the villa and its perch, according to the Xinhua News Agency, fearing that the agglomeration's weight may cause the building beneath it to collapse. The local bureau of city administration attempted to investigate the allegedly illegal construction, but the owner "has not shown up so far." (Photo: Jason Lee, Reuters) Read the rest
