Inverting colors for an animated gif

Does anyone know how to invert the colors of all frames in a GIF? I dont have a frame editor installed and it would take forever to does this one frame at a time.

Heres the image...

Done with The GIMP (took a few minutes to figure out... then about another minute to actually do all the layers). Go into Greyscale Mode (under the Image menu)... Open the Layers Dialog, and then for each layer in the GIF, do a Layer - Colours - Invert. Save (Export as an Animation) and you're done. Smile

Thanks man. At first I thought about putting this in the top-left corner of my table making it look kinda funny with a stick figure running around the cell. But, this shpere thing might look better with a little tweaking.

For some reason when you first load this website, sometimes the top images stretch.

Dont know what paint programs you have but this would be pretty easy to convert. For example I have Paint Shop Pro 6 & 9 and it would be easy to do in either one.

I would just open the gif with the animation viewer. Then select all images in it and open them in the Paint app. Since the image is black and white it makes it even easier, just pick negative image for each one. Save all the images. Then create a new gif with the saved images, with the same timings and sizes as the original. Save as gif and done.
