Preheat the oven to 350 degrees F. and grease an 11 inch tart pan.
In a food processor or blender, blend the graham crackers until they are fine.
In a medium bowl, add the graham cracker crumbs, sugar, and melted butter. Stir together until well incorporated.
Press the mixture evenly to the edge of the pan.
Bake for 10 minutes, then remove from the oven and allow to cool completely.
For the mousse, cut the tops off the strawberries, then blend with the water until pureed. Set aside.
In a large bowl, beat the heavy cream, cream cheese, powdered sugar, salt, and vanilla until soft peaks form.
Add the 4 tablespoons of water and gelatin to a small bowl and stir together. Add 2 tablespoons of the pureed strawberries and stir. Heat the mixture for about 10-15 seconds in the microwave, until warm to the touch. You can also place the water and gelatin in a small saucepan and heat over low heat for about 1-2 minutes.
Add the honey to the rest of the strawberry puree, then stir the gelatin mixture into the the rest of the mixture.
Gently fold the pureed strawberries into the whipped cream until completely incorporated.
Pour the strawberry mousse into the cooled tart pan and refrigerate for 4-6 hours until set.
Top with more strawberries if desired.
