Can you explain what im looking at mark?
Probably not, since it is pretty much self-explanatory to me. It'd be like someone explaining to you how to play the flute as "you blow across one end and move your fingers up and down the outside".
The general idea dates back to the Digitalis D'ydii Cluster game, in which players could choose what to use as the unit in which to display price-lists. Want to see how much everything costs in tons of fuel? No problem. Prefer to see prices in tons of gold? No problem. Pick the item in terms of which to express the prices of everything else.
I have so far picked just a few sample items in terms of which to display the prices of the other items, as this is not some generic CGI script but just a few little shell scripts I used at home to create HTML pages which I then uploaded (because I hate navigating my local disk with a browser plus hey this way I can show the numbers to other people in case I might not be the only person curious about them).
