I'm making a map editor. I need some icons to represent the pencil/brush, eraser, floodfill (bucket), and that picker thing (where you select something and the pencil becomes that selection).

I thought google would be the easiest route. For some reason though they seem to be in these "packs" you have to pay for.

Does anyone know a site or have a few icons like these I described that they wouldn't mind sharing? I can scale them to appropriate sizes if need be.

(I hope this doesn't count as a Help Wanted post)
