Originally downloaded 9/15/06. The University of Michigan's Unix Group has built an amazing number of cool-looking Mac OS X graphical tools, mostly for system administrators and web developers, and all open source. iHook provides a set of directives, documented in a file that accompanies the software, which let it modify its own interface in order to run Unix shell scripts with an Aqua coating, complete with such widgets as progress bars and drawers. It sounds a little like another tool I've tried before---Platypus---which is widely used for this kind of task. Of course, Apple's Automator can also wrap a shell script with a GUI wrapper, though not a very sophisticated one. 
I'd like to give iHook a try, too.
Version as tested: 1.1.0
