Akismet Plugin Logo
I'm OCD about all my plugins having a logo. The Akismet 1.0.3 plugin I'm running didn't come with one, so I downloaded this one:
and saved it as icon.png in the Akismet plugin folder.
It's kinda huge at 400x400, so you can reside to something more sensible (like 64x64) before deploying... or not. Vanilla resizes it just fine, and it only displays in the Plugin admin interface.
