Thanks, all! Yes, I thought the frenetic pace of the Sigur Ros song was perfect for a sped up video... now that the video is getting so many more hits, I hope they don't mind. I tried to attribute them clearly.
I think it's the video that helped push the consideration, honestly. I randomly selected this field to do a screencast and wasn't sure how it'd come out. It's honestly not my favorite one of the group that I processed! But I think the judges appreciated seeing the creation of a synthetic green frame in PixelMath from the video.
Anyway, thanks for the support. Without Harry's intro videos, Juan's explanations on the forum (and tireless work on PI, of course), and Vicent's workflow logic, it wouldn't have been possible. I've learned so much from these forum pages and still have a long way to go.
