The concept of making the world better however best we can doesn't lend itself to easy illustration, but in several places online it would be good to have pictures. Subreddits usually have little logos, sometimes with the reddit alien doing something relevant, other times just with an appropriate symbol:

I'd like to make one for r/SmartGiving . Facebook also likes images, and there's currently no picture attached to the dinner discussion Julia and I are hosting in a couple weeks. What sort of imagery indicates "smart giving"?

(This is kind of like picking a good name.)
