Watched a documentary about this woman today . Her creations are just unbelievable . I never thought of maths being useful to art, but having seen the pages and pages of complicated figurework,algebra, equations, fractions and massive workings out for each piece of work that this lady does, to achieve accuracy to one tenth of a mm , I now see it.
( You cant tell from some of the pictures, but these creations pop up from being flat within a book )

Thanks for sharing this link, the work is so intricate, I wish I had the patience to create something so beautiful and fragile.

Ive just looked at her official FB page and gone through the photos. Some of them I just cant believe they could be pop up- like the cups of coffees.
