Most DS Lite cases are themed on something. These particular cases are themed just fine, but it's nothing we've seen before. Etsy craftsperson filmfatale has gone for a generic "critters" design. Someone might filch the idea and use critters in an upcoming game ... which would spawn a disturbing merchandising cycle. Coming soon from a developer near you -- Critters: The Case: The Game: The Case.
Some materials used here are none other than recycled clothing (among other suitable fabrics). That's a pretty good idea. In fact, anyone with a leftover surplus of puffy shirts or parachute pants should probably get to work, because homemade cases are all the rage. Check out filmfatale's store for more stock!
