Basically took a series of screenshots using notarget of a combine soldier.
Well, that makes it sound really technically. I basically got the angle right and pressed F5 as many times as I could in 2 secs lol.
Then I cropped the images and compressed them, bunged them in flash, and saved it as a gif.
Pretty funky animated avatar I think.
Might do some more of some other characters/funky things.
Hope to do a 3d circling type animation of a combine soldier too, but it's a bit tricky.
