Last night, Mike Rose pointed me to this great Leopard tip that allows you to turn your Application folder into a full-screen app viewer. Here's what you do. Navigate to /Applications and select the entire folder (Edit > Select All or Command-A). Next, tap the space bar, click the full-screen arrows and click the Index Sheet button. Bingo: instant full-screen viewer goodness.
Update: My bad. It won't launch the apps -- just displays their icons quicklook-ishly. Still cool.Thanks Sebastiaan!
