1 Introduction



Ever wonder how I made the seemingly complex-behaving, realistic-appearing animation at the top? Making these kinds of animations aren't just putting a bunch of frames together to form something that moves, rather, they have otherwise hidden details that are often not thought of. This tutorial will explain, step-by-step, in great detail, just how I went about making this animation and you can follow along to make your own variation of it yourself and other animated GIFs like it. It's not as complex as it seems.

While going through this tutorial, you'll see many (19) screenshots giving a behind-the-scenes look at how the animation was made. The screenshots on the main document have been heavily scaled down as having 1600x1200 images displayed as is means a high chance of horizontal scrolling and heavy memory usage. To view the full-size version of the screenshot, simply click on it. The screenshot will open in a new window (or tab) and be shown at full size. This way, you can read along with the tutorial and view the full-size screenshot to see what I'm talking about.

2 Tools used



I only use two main tools: a spreadsheet and The GIMP. The spreadsheet (Microsoft Excel 2002 in my case) is used for all the computations I do and for the planning. The GIMP is what I use to make the scenery with and to build each frame.
