How about... The diapositives, motion blur, scratched wooden surface background and shadowed borders (simulated lighting)? Those are the main design elements of the site, and are all skeuomorphic.
Most "3D hacker interfaces" in Hollywood movies aren't skeuomorphic, yet they blink and rotate and blur and zoom all the time. Same for many Asian TV channels. In what way is worrydream.com bad that doesn't apply to these elements, and why is it caused by textures from real life? Aren't they just all confusing because they are doing too much at once?
