After seeing jdogg's animation thread, I decided to download Pivot and give it a try.
I'm new at this, but it turned out better than I had expected. If anyone wants to try to make a better one about anything, go ahead, and feel free to post the results here.
I don't remember where I downloaded Pivot, but you should be able to find it through Google. It's a simple and FREE program.
Here's the animation I did when learning about easing.
As you might see, his head doesn't move at the same pace all the time. This way you can make it look less choppy without using more frames. A better description and example can be found in the guide.
The Pivot file from FileFront is a .exe file. Exe is short for "executable"... Meaning you can run it.
It's sort of hard to tell you how to open it when you don't say what file it is.
If it's a RAR, you need to unpack it with WinRAR If it's a torrent, you need a downloading program which handles torrents, such as uTorrent or BitComet. If it's an executable, you don't need anything but the file.
The ones I use in the animation I just showed you I drew myself, in MS Paint.
However, in the project I'm currently working on I'm using a bit better blood splatter, from a site called droidz.org. They've got a bunch of .STK pictures you can use, including vehicles and weapons.
And yeah, I'm sort of lazy too, but after you make one animation in which you actually try hard you'll notice how awesome your animations actually can be, and you'll realize that it's totally worth it.
