I've been reporting lately on how the classroom can use Skype to open up to the bigger world.

Former Sen. Bob Dole used Skype video calling to tell a Kansas class about his World War II experiences.

And sci-fi author Cary Doctorow told a Colorado classroom why the local school board should approve his book.

Now CBS 13 in Sacramento, Calif., is reporting how an 18-year-old high school senior battling cancer attended his graduation via Skype video calling.

Steven Lee, just months from graduation, was diagnosed with leukemia. But reporter Ron Jones shared how Steven was able to attend the graduation at Rosemont High School while he was in San Francisco undergoing chemotherapy for leukemia.

Jones said "With a laptop in hand, Steven watched the entire graduation from his hospital bed, listening to every inspiring speech and song, but what really made it a true graduation experience is when he was able to virtually walk across the stage while I accompanied his mother to accept the diploma.

"It was quite an experience, especially being in the hospital and dealing with IT guys and dealing with my health as well," Steven said. "Pretty awesome."
