I have just uploaded the beautiful iBonsai app to my iPhone.
With a tap of your finger, iBonsai’s sophisticated generative algorithm begins growing a unique digital tree. No two bonsai trees are the same! After about 30 seconds of growth, a mature bonsai becomes a beautifully rendered image in the sumi-e style of Japanese brush painting whilst an ambient music generation algorithm produces a subtle soundtrack which never repeats!
The iBonsai algorithm produces an almost infinite variety of trees: you might get simple, elegant shapes or twisted, complex creations. The randomness is the source of its beauty.
