Rhombille tiling Rhombille tiling In geometry, the rhombille tiling, also known as tumbling blocks, reversible cubes, or the dice lattice, is a tessellation of identical 60° rhombi on the Euclidean plane. Each rhombus has two 60° and two 120° angles; rhombi with this shape are sometimes also called diamonds. Sets of three rhombi meet at their 120° angles and sets of six rhombi meet at their 60° angles. The rhombille tiling can be seen as a subdivision of a hexagonal tiling with each hexagon divided into three rhombi meeting at the center point of the hexagon. This subdivision represents a regular compound
A Plane Is Born packed programme sees major progress on the plane with the rudder assembly completed and the fuselage top on and finally bonded. Back at Staverton, Mark learns how to talk - important for a presenter but vital for a pilot as he masters the rudiments of radio communication. In another look at other kit-planes, we meet fellow Europa constructor Peter Kember who was the first ever to home-build a Europa Kit. - All Revved Up It's a red-letter day down at the workshop as the brand new engine arrives with Europa's Andy Draper. Mark takes on the delicate task of fitting
