How to create a tiled gif (repeating the same small gif image in a tiled background)

I have a gif image with a rather low resolution (500x200 pixels) which I would like to use to tile a wallpaper background (size 1920x1080 etc.) showing the same frame (or a different frame) on all copies. The output should look like using gifview and enlarging the view area. Is there a script to do this? (I know that I could split the gif in frames, then copy each frame to tile the bigger canvas and finally combine all back to a gif animation, but hopefully there is an automatic way to achieve this.) Thanks for any help.
