Just an FYI....
Check out Masters.com during the tournament for sure, but even before it starts the site is worth browsing. Lots of new video, hi-res photography, interviews, history, info on all 18 holes, etc.
During the tourney there will be lots of live streaming and hole flyovers, etc.
Shameless bragging section: My son is again the webmaster for the site (via IBM) and he is also the technical lead for the iPhone and Droid apps that are now up and available for download at the site. (He's there, but no, he can't get me in to the event...still the toughest ticket in sports)
