I’m working with a client who wants a motion graphics representation of how their product reduces the amount of airflow through cracks in walls and floors. Essentially, I’m looking for 3D (looking) elements of walls, floors, etc. Imagine if you were watching a home improvement show and they showed you a cross section of a new wall they were installing. I want to show with animated arrows how airflow won’t be able to penetrate the wall/floor after my client’s product is installed. I’m looking for either an after effects file (video hive) with these elements, or a graphics (graphic river) file that I can then animate. Any and all help is appreciated.
