Smooth Wiggle
A smoother version of the standard wiggle expression that eliminates jerky motion.
Expression Code
// Smooth Wiggle
freq = 2; // How fast it wiggles (per second)
amp = 50; // How much it wiggles
octaves = 3; // Smoothness (higher = smoother)
amp_mult = 0.5;
wiggle(freq, amp, octaves, amp_mult);
