As discussed in the earlier BBS, recursive, feedback loop would strengthen the potential of grasshopper.
You can write shape optimization, cellular automaton, interactive game, etc with the feedback loop.


My idea for the interface for feedback loop is to use timer-like components to connect the output to the input as the screenshot attached.
The example represents an oscillating surface that changes the velocity every 1 second.
If timer triggers the update of the input value from the output, it won't make it freeze.
