Then, browser vendors [Apple in particular] developed a method for displaying HTML elements in 3d space and it occurred to me that this would enable me to use the box sides to once again form, well, a box. Since an illustration for the bottom was lacking, I used a sixth image I found at the same location to complete the box.
This left me with a nice perspective picture of a box but stil only showed three sides at best. What was needed was a way to rotate the box using a pointing device. I attempted to cobble together something myself but this turned out to be much harder than I anticipated: it involved complicated mathematics and if anything, I am sorely lacking in math skills. So again I turned to the net and lo and behold, after some effort, Google pointed me to Dirk Weber's excellent traqball script. Putting it all together resulted in this.
