Looking to replicate this script

I am looking to Looking to replicate this script (grasshopper + firefly) but unsure what all the components are. (Very new to grasshopper!)

Thank you!

You’ll need the Firefly plug-in for some of them. Components I recognise are:

  1. Data Recorder
  2. Mass Addition
  3. Panel
  4. List Length
  5. Series
  6. Construct Point
  7. Nurbs Curve
  1. data dam with additional input

Thank you very much! You don’t happen to know the one above Interval?
