Google's new thingy is exactly what I was looking for. Now I just need a way for the parts outside of the round to show up as translucent instead of white. Ideas?
You'll need to copy it over to a format that supports transparency, so just copy-paste into a new file. Then choose the select by color option, click on any part of the whitespace, and ctrl-x to delete it. You should see a checkerboard pattern in the background where the white used to be. Then you can scale or whatever and save as a GIF.

PS - alpha layer has to be turned on before you can successfully delete whitespace.
