This caught my eye, from molistudio in Buenos Aires, where “the mechanized routine” is apparently way more interesting that where I live!
I love impossible machines, and these are really pretty, beautifully rendered in exquisite (virtual) materials.
I strongly suspect that these renderings are based on 3D models, many of which actually could be built with laser cutter, 3D printer, and simple parts.
