This is an After Effects experiment where I used Trapcode Form to generate an interacting 3d shape. Several layers are used to fake the shape's interaction, and clever particle visibility range helps to sell the credibility. Trapcode Particular are used for the subtle particles and Red Giant's Looks to give it a final touch.
Give me a thumbs up and let me know in the comments if you would like me to make a tutorial of this After Effects project!
