Disable the Swoosh animation for Mac OS X Spaces
So, as it turns out there’s a way to disable the motion sickness-inducing Swoosh! animation that happens when you switch between Spaces (virtual desktops) in Mac OS X.
This appears to work on my 10.6.5 machine, but I haven’t tested it anywhere else.
defaults write com.apple.dock \ workspaces-swoosh-animation-off \ -bool YES && killall Dock
