Since you are a calendar site, the "weapon" here is a thumbtack firing a calendar on a couch in the cross hairs to encourage people to schedule and do activities. So no violence involved and says something about your site :) I hope this makes sense. Let me know if you want to see any changes. Thanks!
#80 is clearer. It makes sense when you explain it, but the calendar reference is not obvious just by looking at the logo. i am not sure how you mightmake it more self explanatory
