Apple has this amazing feature called 'Large Type', chiefly implemented into Address Book. When you look up a contact, you can right-click the phone number and click 'Large Type', and it will display it very largely across your screen.
This function is relatively popular for many uses. Users who watched Leo Laporte on TWiT.tv on weekends will see Large Type being used to display wrap reminders to him during his radio show when his iMac is on camera.
As far as I'm aware, the only ways to invoke this are (1) the Address Book function as demonstrated above, or (2) directly via Quicksilver's Large Type plugin, or (3) Applescript invoking a function of Quicksilver or some other application that supports Large Type.
Since I've stopped using Quicksilver, and don't use LaunchBar, I'm left high and dry for putting arbitrary text into a Large Type banner.
Since it's obviously a core feature of OS X, how do we invoke it with arbitrary text under Lion?
