Flower pictures generated by computer code, by Daniel BrownPublished19 November 2013Image caption, Check out these beautiful computer-generated flowers. London-based artist Daniel Brown has been creating them for 10 years. "It started off as a demonstration of computer programs," he tells the BBC. "What I found was that people were mesmerised by them."Image caption, Two different mathematical formulas create the pictures. The first generates the shape of the flowers, the second decides their colour and patterns.Image caption, The flowers appear as "never-ending" digital animations when displayed on a screen linked to a computer. But you can request a still version too.Image caption, Time-lapse computer programs normally used for making video games, show the flowers seeming to "grow" on screen.Image caption, Daniel says it would take two to three weeks to create each artwork if he dedicated himself to them all the time.Image caption, The Flowers series has been exhibited at the London Design Museum and the Victoria & Albert Museum. More recently Dundee's D’Arcy Thompson Zoology Museum commissioned this piece.Image caption, Daniel's also done projects for Lady Gaga, Sony PlayStation, MTV and Hello Kitty.Image caption, Daniel says he never intended to specialise in flowers - he only experimented with them to begin with to get used to the software.Image caption, Apple's head of design Jony Ive has previously complimented the work. "It is technically innovative and emotionally engaging, but also gives us an extraordinary amount of freedom in the way we experience it," he said.
