Part of 'best practices' for any project (software or other) is to have a cool, identifiable iconic image or graphic associated with it. This is important for marketing and brand identification amongst the consumer.

Thus, THIS project needs a graphic. Submit your ideas!

Are there guidelines and 'best practices' for iconic graphic selection? Simple, small (but scalable), not too spatially complex???

well, best practices made me think of halo (no, not the game). Started to look for a free clip-art or iconic halo image. this one's a little silly, but it's a start.
