From the developer:
The idea is that no process of creating the flowers is hidden from the computer, no bitmaps are used and as few human decisions are hardwired into the software as possible. If the computer had the capability, it should be able to think and feel it’s way through as much of the creation of the flowers as possible. A self-funded project, Hana is about giving something back to the computers that help you do the work every day.
