Button image collections?

Has anyone found good button image collections to use with Roomie, or is anyone willing to share theirs?

Right now, I’m just looking for the A-yellow-triangle, B-blue-square, etc. buttons used on Cisco remotes. Sure, I can find pictures of a Cisco remote, and clip buttons out and run them through PhotoShop, or take my own photos, but seems silly for me to re-invent the wheel if somebody else already has.
