I've had loads of people ask me for my default icon, and I'm happy to share provided the orignator gets credited. It was my birthday present, but it'd feel wrong to be selfish about it. On the other hand I've seen it turn up in places where it had no business being and without credit, and that's just plain rude.

What you need is one that goes This icon is FUCKING MINE
