Using Generate you can create beautiful graphics that grow and evolve using a concise scripting language (based on the Context Free language, lightly altered for Android).

You can share scripts with others (shared scripts should work on Aza Raskin's Algorithm Ink site and (mostly) work in the Context Free software).

Once you have a script working you can use the above versions to produce much higher resolution versions (consider Generate as a kind of sketch book).

Comes with many sample scripts and integrated help/reference.

On Android 4.0+ it includes syntax highlighting, fullscreen mode and many other small improvements.

Uses Aza Raskin's Javascript implementation of Context Free (source code and other links are contained within Generate).
