After playing with the new Interface Buider a bit, I saw a very amazing feature. You can apply “Core Animation” to any view (that is, custom NSViews, OpenGL Views, WebKit Views, NSProgressBar, anything!) That means you can “post-filter” any view with any combined stack of the well-known CoreImage Filters! (Blur, CMYKÂ Halftone, Kaleidoscope, etc…) Very cool indeed!
On the image, Remote with a “cmyk halftone” filter applied, running at full speed and no extra CPU cost. All the work is done in the GPU, neat.
