I wouldn't really know where to start, but I use BB for its minimalist and in control feel. Beauty, in simplicity~ That said I think it would be a fantastic idea to do a video run through of blackbox. Maybe on another installation rather then messing with my own.
My idea would take us through installation, style customization through the RC file and GUI, basic menu setup and black bar tweaks. Not sure which plugins would work for this type of demonstration though and would most likely be doing it on a laptop thats not my own so video quality may suffer a bit. After thats setup, someone could record a voice track possibly giving verbal ideas of what is being done, length wouldn't matter because video editing and stuff.
Random, when I clicked on the video just now to see how it was doing and one of the recommended was "what do you do if a black box keeps popping up", obvious help for some windows problem but my mind automatically said "you set it as shell".
