I have seen that video before --- I can't rock it though.
I did have one balloon creation that I will have to recreate and take a picture of. I made a balloon football themed hat. It had goal post in the college color that we were at, green for the hat part (grass), and a white arched balloon with a football attached to it flying through the goal posts simulating a field goal. It turned out great and I loved it, but I forgot my camera at home....

When I recreate it and take a picture of it, I will make sure to share it here of course.
