How to Make Mac OS X Get Weird

You can shift-slow-effect on other effects too. Try shift-dashboard and -expose.

Even more useful - turn on "developer dashboard" (a hidden preference), and drag a widget & close the dashboard at the same time. You'll get the widget on the desktop (floating). Put it back similarly.

It's not possible in Snow Leopard but in Tiger/Leopard you can open up the nib files for various system applications and mess with them. Things like adding CoreImage filters to views usually worked ok; I recommend the bloom filter combined with a white-on-black terminal.

That's pretty neat.

Though I think "command-tabbing quickly" isn't a very convenient thing to do...much better to add a "sleep 2 && " in front of the command line (say), so that you can execute it immediately and have it take effect right about the time you're ready for it.

So basically this is Apple Store fun. Try: Open terminal, open screen, sleep 3000; while true; say "hilarious thing you want the Mac to say"; done Close terminal.
