I just found about this new photography light coming out soon called The Kick. It’s a full-color portable photography light that can be controlled from your iphone. All lighting parameters (brightness, color, etc) can be adjusted in real time from an iphone app. You can even play a video in the iphone app to drive the light color in real time.
It connects via wifi to their iphone app, and they have an API available for third parties.
Support for this light would be a great addition to iStopMotion iPad. Being able to set up keyframes for light parameters, for instance, would be very powerful.
