• Making a first gif with Processing
• Loop from periodic function and offset (Processing)
• Noise propagation (Processing)
• Replacement technique (Processing)
• Replacement technique with 2D grid of objects (Processing)
• Motion blur template (by beesandbombs) (Processing)
• Drawing on paths computed by steps/simulation (Processing)

Note : I’m not explaining the basics of drawing with Processing. This is focused on gif/loop techniques, assuming you already know how to draw with Processing or similar framework.
