Usability professional Jason Valalik sent us pictures of his homemade iPod koozie (Or is it cozy? Anyone?). While we can't say that he's the first one to think of this, we're pretty sure he's the first one to actually follow through with the idea. According to Jason, the Koozie is easy to make, protects the iPod, and keeps it cold on those hot summer days. It's not very pretty, although he promises us it's just a prototype.
