Surely there must be some budding smartphone auteur out there who needs to invest deeply in the feature-length film they're shooting on their iPhone 4. For anyone else, Zacuto's Z-Grip iPhone Cinema Kit might be a bit excessive.

The kit builds on Zacuto's $300 Z-Grip iPhone Pro Stabilizer by tacking on a $199 articulating arm, which itself is handy for attaching the $395 Z-Finder Pro. But before you say "for that kind of money, I could just go and buy myself a real camera," listen closely to the nice men in the video: it also works with model trains. SOLD! [Zacuto via Buzzfeed]
