Meet the Joobot CamBuddy Pro: a DSLR controller that connects Canon and Nkon DSLRs to your smartphone through Bluetooth and WiFi, allowing you to change settings, get a live view, and do a whole lot more. CamBuddy Pro comes with sound/light sensors, a laser detector, a receiver and a transmitter.
The device lets you connect up to 128 cameras for a bullet time footage. It will be on Kickstarter in September.[Source]
