We're all familiar with the Speck Artsprojekt iPhone cases, right? Good. Now, if you're searching for a funky case for your iPhone 4, look no further than Best Buy.Coming in short supply, these limited edition Speck Artsprojekt iPhone 4 cases ($40) will be appearing at select Best Buy stores in Illinois, Florida, and Texas, and come with a collectors card insert that tells you about the artist. The cases will come with an artist-designed cloth back plate, and a hard shell to protect your device. I'm particularly fond of the Tron-like one here (which also kind of reminds me of Tokyo) called "Night City," but find all of the cases to come with tons of personality! Check 'em all out below!
