I wrote a application for smart phones (it'll be opensource, so no money involved in case you mind) which displays historic events which happend today some years ago, in other words, you would call the application "Today in History" or "This Day in History".
I'm searching for a application icon which shows two facts:
- The historic feature of the app
- The relation to the current day.
Until now, I choose a simple (flipping) calendar like the one below. This icon does not pay attention to the first point and it can easily mistaken for a calendar application. The only reason why I choose this icon is, that in Germany such kind of historic facts are typically written on the backside of calendar sheets, but I think this is far from clear for the user.
So: How to you put both, the historic context and the relation to the current day into a clear icon?
Other ideas (thanks Alex), are historic sites like the Acropolis or another temple, but here the second fact is lost.
