In geometry, a spidron is a continuous flat geometric figure composed entirely of triangles, where, for every pair of joining triangles, each has a leg of the other as one of its legs, and neither has any point inside the interior of the other. A deformed spidron is a three-dimensional figure sharing the other properties of a specific spidron, as if that spidron were drawn on paper, cut out in a single piece, and folded along a number of legs.

TSP art is a type of line art based on the Traveling Salesman Problem. An image is first discretized into black points on a white background. The points are then treated as “cities” in the TSP problem. An approximate solution to the TSP problem is calculated and drawn. The result is striking approximation to the original image. Remarkably, the path never crosses itself. Read more here.

Gijs Van Vaerenbergh, a collaboration between young Belgian architects Pieterjan Gijs and Arnout Van Vaerenbergh, have built a see-through church in the Belgian region of Haspengouw. The church is a part of the Z-OUT project of Z33, house for contemporary art based in Hasselt, Belgium.

The church is 10 meters high and is made of 100 layers and 2000 columns of steel. Depending on the perspective of the viewer, the church is either perceived as a massive building or seems to dissolve – partly or entirely – in the landscape. On the other hand, looking at the landscape from within the church, the surrounding countryside is redefined by abstract lines.

The design of the church is based on the architecture of the multitude of churches in the region, but through the use of horizontal plates, the concept of the traditional church is transformed into a transparent object of art.

That is so cool!

In the Game of Set, the objective is to find a set of 3 cards according to certain rules. Put simply, for each property [shape, color, number, shading] each of the three cards is either all the same or all different. Presented here is the worst-case scenario deal - 20 cards with no valid sets.

One of my favorite card games!

Felice Varini, a Swiss artist now based in Paris, paints simple geometric images that when viewed from most random vantage points appear to be a jumbled collection of fragments, however when viewed from a special single point coalesce into a cohesive planar element.
