The Media Sharing category is for publishing videos, images, interactive compositions and other digital files to share with other people, and general discussion about the creation / usage of these files.
There are a few special sub-categories for common formats like movies, Interactive Shader Format (ISF) and Quartz Composer, but anything related to real-time visuals is acceptable.
Seeking a digital image VJing tool/ visual instrument? As a mock-up of my idea, I am assembling: a screen, slide projector, light table full of 35mm slides from which I will pick one slide at a time, insert it into the slide projector to display on the screen, use the light table to preview the next image, eject the first and insert the next, etc. Is there a way to do this digitally with .jpeg images on a Mac?
