RunSnakeRun is one of my older projects.  It's a small utility which loads HotShot profiler data into a sortable GUI table.  It now also supports cProfile/profile module profile runs.  I've also updated it to work with modern wxPython and numpy instead of Numeric (it uses numpy to speed up loading of very large HotShot profiles).  Oh, it also now uses setuptools to automatically register a runsnake script to launch the GUI.

The GUI is nothing special, but it gets the job done when you want to track down hotspots in your code.
