Colored Light Strokes and Streaks
Mattrunks on 3D Stroke, plus some alternatives
By Rich Young | July 20, 2011
In a new training video in English and French, Colored Light Paths with 3D Stroke, Mattias Peresini (aka Mattrunks) shows the basics of Trapcode 3D ??Stroke. There were been a number of similar tutorials in days of iPod and graffiti yore, but they're harder to find now that the effect is not as popular. Tutorials by Brad Chmielewski (Animated Cartoon Arrows) and Nick Campbell (How to make 3D Text and use 3D Stroke in After Effects) are still easy to find though.
A little further afield are Spirograph designs, which are a popular use of expressions; see Spiral shaped motion paths, Spirograph-style pattern generator in AE by Chris Zwar (inspired by the spirograph tutorial from Ayato), and Dan Ebberts on spirograph expressions. Along those same lines but using Particular and expressions is Generate Your Own Splendid Spirographical Designs by Christopher Kirkman on Aetuts+. Variations on spirograph patterns can also be made in After Effects with standard tools. Other similar tutorials by Satya Meka (on the Radio Waves effect) and others were referenced in A few spirographs in After Effects at AE Portal archive.
Here's a preview render for new tutorial by Mattrunks, which was translated by Dominic Pons:
