aLgrTepy2e (pronounced "LargeType2"... it's a big-endian/little-endian thing) shows your selected text at huge font sizes. Hooray!
Drop it in your app folder, log out and back in again, then experience a brave new world of shadowed white-on-black text and draggable translucent windows! Just choose "LargeType" from the Services menu (or, in 10.6, right-click for the handy contextual menu).
Manage your font library so you can have easy access to your favorite fonts.
