Here's my new version.
Basically all I did was fix an error somebody made when they spilled yellow paint on half of the flag. It all washed out very nicely in the end.
The black stands for anarchy. The yellow from before was just paint, it's really black underneath the yellow. It's all black because anarchism doesn't need stupid borders running right through the middle of it. In fact, it's pretty incompatible with anarchy. It's also plain and logo-free because it also doesn't need to be peppered with disagreeable symbols. That said, black is a color that goes with everything, and you should never think that it only goes with your one favorite color.
