Oh, those leaning towers are so yesterday. Tech-watching sites, rather, are talking about a tower that does not lean; it is just as interesting as it is a self twisting tower. This is the Urbach Tower.

(Tech Xplore)—At first sight drawing objects in the air has you rubbing your eyes in disbelief and then you realize you are looking at a 3D pen in action.
Wood is an organic material; in the strict sense it is produced as secondary xylem in the stems of trees (and other woody plants). In a living tree it conducts water and nutrients to the leaves and other growing tissues, and has a support function, enabling woody plants to reach large sizes or to stand up for themselves. However, wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber.
People have used wood for millennia for many purposes, primarily as a fuel or as a construction material for making houses, tools, weapons, furniture, packaging, artworks, and paper. Wood can be dated by carbon dating and in some species by dendrochronology to make inferences about when a wooden object was created. The year-to-year variation in tree-ring widths and isotopic abundances gives clues to the prevailing climate at that time.
