i'm just working on my little game and got some empty brain, no idea, maby somebody can help me, if he has a idea...
I need two icons in a kind of "bubble" or something like that over the head of NPCs, where the player can buy things or can talk with them (should be just in general "buy" and "talk").

(click to enlarge).
On the left you see my pictures for this in gimp, but it doesn't fit in a medival world.
I dont like my actual version and maybe somebody has got a better idea or some food for thoughts?
