In a saucepan bring the water and 1/2 cup sugar to a boil. Let cool then pour into a shallow pan and freeze overnight. The next day, scrape the surface of the ice with a metal spoon to make shaved ice. Store in the freezer until ready to serve. To make the toppings, puree the raspberries with the remaining 2 tablespoons of sugar and strain to remove the seeds and set aside. Blend the grape juice concentrate with the mint leaves in a blender and strain and set aside. Whisk together the citrus juices and honey and set aside. Using a large ice cream scoop, scoop a ball of the shaved ice onto 4 cones. Drizzle with various syrups and serve immediately.
