Flow based programming

Anyone interested in developing a language for node/flow based programming (for example like vvvv) ? 

Here are two screenshots from my prototype. Features that should work:

- Defining nodes in a custom aspect

- Ports with primitive types

- Language for accessing ports

Features that would be nice:

- Visual nodes (should be possible because the nodes are defined using the standard editor) 

- List input and output

- Ports with custom types

- Node updates at a defined interval

- Defining nodes using plain java classes with some lightweight dsl instead of the old approach ( inspiration)

- More than a handful test nodes

I'll upload the current prototype to Github soon. Any feedback or suggestions are appreciated.

Custom aspect for defining nodes:
