WARNING: Be careful with Periodic runs. If the amount of time to re-calculate larger graphs will lead to never-ending runs if the time to execute is longer than the refresh rate.

On a more positive note: I still love this post by @Zach_Kron in the geometric formulas in design script thread. Really inspiring use of periodic runs.
