Each file is graphically represented and named, and function calls are graphically represented inside of each source file. The end result is a 180MB vector PostScript file. You can get the source code and then render it yourself, or if you just want to get the big finished poster, send an e-mail to Linuxcare or contact EverythingLinux if you live down under. BTW, it took us about 5 hours to get that file to print at a print shop down at LWE - that much vector PostScript really tested the limits of their big printers!"
