Extremely powerful for it had a slit. Now it's dead.
Linux users have now tooken it's soucecode and created fluxbox, which is extremely good and much better than BB4Win. Fluxbox DEVELOPMENT VERSION offers Taskbar, and Icon Bar, not needed. As well as a more customizable taskbar and fbdesk for icons. Plus the remarkable tabbing engine, allowing you to group your windows automatically and manually.
Window users can now sort of enjoy Blackbox on Windows as a shell replacement called BB4Win. You can still enjoy your internet explorer by using it instead of explorer for a filemanager. BB4Win isn't as good for sloppy focusing and it doesn't allow you to have tabs, or to shrink the taskbar to as tiny as you want it to, but it's still a good blackbox shell for windows and a good replace of Explorer.
According to most theories, the black box is a blackened lock box containing precisely one thousand condoms. This box, only opened once every thirteen years to a certain individual of superior strength. Once opened, the box opener, or the Jehosaphat, must use every single condom in a 24 hour period. If he does not complete the task, his sexual organs will implode violently, effectively killing him. If he successfully completes the task he will be blessed with a cock of magical size and powers. The length will be precisely 6 inches, when folded in half, before getting up. Also, the victorious Jehosaphat will have complete control over his crotchal region. Erection and ejcatulation at complete whim.
