Quote: "The charts are intended to be interactive such that Internet explorer users may click and drag the starships within the charts to arrange them in whichever way they please. I am working on incorporating the same feature for Netscape and other web browser users. The site is very Graphics intensive by nature and therefore is targeted towards a higher bandwidth connection (DSL, etc). It will likely bog down dialup connections."
