genie come back

For a long time Macs had an easter egg where if you held the shift key while hitting "minimize" it would have a nice slow motion view that let you appreciate the animation (the Genie effect)

For some reason they removed it by default but DaringFireball points out you can get it back:

defaults write com.apple.dock slow-motion-allowed -bool YES; killall Dock

The Mac "minimize" view is always kinda interesting. It's sort of like putting something on the shelf, like how it takes it out of the normal cmd-tab flow.
