You should check out the new website that the British Museum has created to provide access to Codex Sinaiticus. This is the website that prompted the aformentioned articles on the Codex. The site is actually quite neat, though some features appear to be non-functioning (at least they were for me using Firefox 3.5). Here is a screen grab of the site illustrating its function. At the top are a series of drop boxes that allow to quickly and easily find the folio page you are looking for using the standard chapter and verse divisions.
Another column near the image displays the transcribed text, while a box at the bottom displays the translation in English, German, Greek, or Russian. This is a cool tool to explore and I look forward to playing with it more.
