This i'm using now (an'
lovin' it). Another tool originaly by the creator of Quicksilver, this plug-in enhancement for Terminal.app was formerly called
Visor:
- TotalTerminal
a systemwide terminal window accessible via a hotkey, much like the consoles found in games such as Quake.
To maximize its coolness factor: throw in a background animation, by using a
quartz composition. Some nice (as well as free) examples are available for download from a page by
Futurismo Zugakousaku. (i like 'Fish Crowd' and 'Particle Fish' the most)
