This video has been round a while now (29 July 2007), but I never added it to happyfolding.com up until now. It's the only video thus far where I added the instructions afterwards (using my boyfriend's fancy microphone.) Given that it was one of my first videos, I think the result is quite excellent. No first-person perspective, but other than that I'm still quite happy with the quality of the instructions.
In the video, the modules used were folded from 52.5mm by 74.5mm sheets of paper. The resulting model has a diameter of approximately 13cm.
