Can't find tutorial: Apply Image (I think??)

[andyapc]

All right - I think I'm going crazy. Last night, I was going through the PS tutorials, checking off the ones that I wanted to try today. I know that I saw something called "apply image" or something like that. I'm pretty sure it was written by Emma and it had something to do with using multiple photos that were exactly the same size. I can't for the life of me find it today.

Was I looking at a tutorial? If so, I can't find it now! :(

It was a really cool effect and I really wanted to try it tonight. Can anyone help me find it?
