LeeLABS have created a variety of clocks made of concrete that all use a parametric modelling algorithm to get their unique radial patterns.
They also plan to make it possible for anyone to create their own custom concrete clock by playing around with the parametric settings on the Para Clocks website.
They have created a KickStarter project video about the clocks – here.
The Slab Vases consist of rings of Silestone, which have been slipped over a metal bracket to create a sculptural vase. The rings vary in size and are cut so the shape of the vase changes with each assembly.
You can watch a short YouTube video about the making of the vases – here.
