A time series is a series of data points indexed in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data.
Timer component is one of the most useful components in grasshopper yet its effectiveness in design has not been fully revealed. In this attempt, a simple pendulum effect has been created by solely using the timer component. The component is used as an increasing series of input (numbers). This is a very effective technique to observe all the alterations of a design by generating a set of iterations. It can also be used in creating virtual models of dynamic structures.
