This is Pixmap-Based theme to customise GTK+ to look similar to BlackBox.
Please feel free to play around with it, and improve it.
Improvements can be made to the look (by editing *.png images), or the feel (by editing gtkrc).
I hope to write an engine eventually, which will get colours from ~/.blackboxrc. More info is available at http://www.netspace.net.au/~dww/blackbox.html.
This theme is obviously GPLed.
