Matthew Turk's Homepage - GLOYD

I have created a standalone application for OS X that takes video from an iSight and puts it through up to two gravitational lenses, allowing for interactive modification of the parameters. (The original, non-interactive version is still available as a packaged quicktime file, easy to include in presentations.) This program was designed with the new MacBook line of laptops in mind, as they feature built-in iSight cameras. (Although, I don't have one of those, so please report any bugs!)

Please do let me know what you think of it. I ask that if you use it in a talk or a class, you credit KIPAC/Stanford and me. Any improvements and new versions will be announced on this website. (I plan to at least release a version that indicates time delay via coloring the image.) Phil Marshall provided valuable guidance on this project.
