Abstract: HTML code is delivered in a received message or browser window which causes an invisible window to be created. More precisely, the window is at a coordinate which is beyond the coordinates on the computer screen and, therefore, is not visible to the user. The invisible window executes additional HTML code or may draw it through the Internet from a remote cite. The additional HTML code may produce further, invisible windows, which may be animated, and are independent of anything which appears on the computer screen. For example, the user may be presented a window on his screen which offers a free stock ticker, in exchange for being presented with periodic commercial messages.
