Using a shaved ice machine, shave 12 ounces of ice into a cup or bowl. Create a dome-shaped top with the ice. Beginning on the left side, pour peach flavored syrup in a straight line, covering 1/2 of the ice. Next, pour strawberry flavored syrup on the right side, in a straight line, covering the other 1/2 of the ice. To finish, garnish with fresh peach and strawberry slices and serve with a spoon or a spoon-straw.
