Really liked the plugin, wanted to contribute but I don't do codes. (；´д｀)ゞ
Here's little something I made for it.
Please feel free to use.

This is really cool, thank you! （＾▽＾）
Can you include the word "TNT" (like on the block) so that when people see the logo, it will be easily searchable? This design is really cool!

Do you mind making an icon as well? Thanks!

I thought of removing the third "T", but that makes it "WEAK", whilst the plugin doesn't make TNT weaker in any sense.
It might need re-scaling when used in context.

Seems good to me! If you're comfortable with it, please send a pull request with the artwork located in Resources/Artwork. This will allow changing the logos in the future by pull requests if necessary, while not having to update existing links.
