Emilio Gomariz made some new OS X GUI animations and I think they are stunning.
“Alternated Gradients” is combination of 5 videos of the screensaver “Spectrum”. BTW, he also has this screensaver as his desktop wallpaper.
“ctrl tab torus” is an animation created by using the ctrl + tab keys in Photoshop to cycle through the open windows.
“Twist Choreography” – the effect is just created by opening text files from the dock.
“Open_Close.txt – Default – this one is similar to the last one, just that each file opens as a colored square.
