The first one was a Spuffified version of the album cover of the Grease soundtrack.
Spuffy is the word
It's got groove it's got meaning
Spuffy is the time, is the place, is the motion
Now, Spuffy is the way we are feeling
Then I did three manips + wallpapers based on screengrabs from "You're the one that I want".
Danger Ahead #1
Danger Ahead #2
Album cover manip: I don't remember where I found the image of the album cover I used, but it's all over the Internet. If you want to see the cover while listening to the soundtrack, look here.
The font I used for the Spuffy logo is the appropiately named "shagadelic" font by Digital Graphic Labs from dafont.com. The photo of SMG I used is by Vera Anderson. (Totally stolen.) The photo of JM I used is by Blake Little. I have no link for that one. I got it from Civilized James, which sadly no longer exists. The stake is a Sideshow Collectible prop; I got the image from here.
Wallpapers: the Buffy screenscaps are from the HD episodes I downloaded from hdbuffy.tumblr.com. The Grease screencaps are from the "You're the one that I want" video someone kindly put up on YouTube. The carnival photos are all by me. Coincidentally, there was a carnival in my street right at the start if the round, so I took advantage of the opportunity.
