I'm looking to create the phrase ".com" but have it orientated vertically (running bottom to top, opposed to left-right.)

I know I can use a graphic, but the page I am using it on is likely to be high traffic and bandwidth will be a large consideration. The rest of my site uses CSS for the titles and a series of IE only filters to brighten it up.

Is there any alternative to creating a graphic, I foresee it to be much less bandwidth intensive to have a <td> with text set to a "vertical" orientation???

Is it possible?
