It isn't difficult to make snow cones at home. An ice shaver (remember the Snoopy Sno-Cone Machine?!) creates the fluffiest ice, but you can also make it granita-style or simply crush ice in the blender.
These recipes all incorporate fresh fruit:

• Fresh Fruit Sno-Cones at Epicurious (pictured)
• Raspberry-Blueberry Snow Cones at Epicurious

Or make up your own version, using whatever fruit is in season, fresh juices, and homemade simple syrup infused with fruit or herbs.
