Here's an image I built, doing one of Oliver's Blendtuts! I was highly impressed at how nicely this came together! I shot the photos on my Samsung Galaxy 3, in our driveway (you can see my Town and Country)and composited it in Blender! I showed it to a friend and he asked when we had time to go to the beach. I laughed and replied "That's not even a real sky! It's computer generated! He was shocked!! :)
Note: You can see, in the screen shot, I did this in Blender 2.7
