Several months ago I had planned on joining the Guinness World Records swap and make a card for the microscopic movie "A Boy And His Atom". I couldn't figure out how to make the card look right so I gave up.
I finally came up with another idea. First I used a "Bind-it-All" like machine to make a long film strip. 2.5"x10"
Then I stamped several "frames" onto the paper to see how it looked.
The final card will be 2.5"x7" and only have the first 6 frames.
I might make another scene from the movie.
