This balloon video is by the Amatour. Please visit his website, especially if you are into geometric shapes and math. I have watched many, many of his videos, and his designs are wonderful. However, I was never too good at math, so I don’t always follow what he is doing that well, but it is well worth the time to watch what he can produce. I’ll keep trying. In the meantime, enjoy this sunflower twist. Oh, and don’t forget to check out his YouTube channel.
