Central Florida is a really cool place to view thunderstorms. Here's another shot from another balcony, at a different location, taken with my iPhone 4 and the Camera+ app.
Unfortunately, this storm injured five employees and three guests at nearby Sea World, Orlando. I do recall hearing sirens about 10 to 15 minutes after taking this shot.
The three guests and two of the employees were hospitalized after a near-miss lightning strike. News reports indicate that all have since been released.
