One idea is you could make a comic where the view is from a person looking up out of a grave at their own funeral. People are walking around through this vision crying and stuff. Then you could make a couple more frames where dirt is being shoveled in. The last frame could have the imminst logo and say something like, "You've got a date with your grave and you want to be late."
We can get you some more action orientated, lighter, people talking kinds of comic ideas though if you want. Let us know if you want to try this one at all. I think we can get the concept of a comic like that approved for the newsletter. If we run into some trouble with that we can come back to the drawing board here with examples of some standard comic stuff that could be done for the newsletter.
If you want, you can look through
http://imminst.org/newsletters and come up with a concept peice to represent a topic or two in there. For example, in the "around the forum" section there is a link on the constitution, and one on cryonics. You could say, do a drawing of a guy holding up a pen to a constitution looking peice of paper, or you could say, draw a cryonics tube with a person pushing a medical tools tray outside of it or something like that.
Dont quote me on this, but I think that we can get your drawings seen by a lot of people. We are growing all of the time and could go viral any time really with in the next year or 5.
