Fibonacci and Geometric Doodling

A friend posted this on facebook recently- and it took us on a mathematical doodle journey.  It's just wonderful for all sorts of geometrical patterns.

I believe that this was a link to Vi Hart's youtube channel which now seems to have gone.  If you do a search a few of her things still come up, but most of them are now gone.  The whole family were huge Vi Hart fans, and Willow was inspired to do some interesting geometric maths thanks to Vi.

After some more searching I have discovered that Vi Hart moved to vimeo.  This is a really amazing resource for art/maths/music.  She covered quite a diverse range of areas in her mathematical doodlings.

Whilst trying to find out what had happened to her and her work I discovered that her Dad works in geometric sculptural designs and he has some interesting resources too.
