My initial attempt was to create a "Decoder Card". As you can see I used the tree stamp image, and overlapped it several times to create a blurred effect. Unfortunately I used a red ink that was darker than my plastic decoder lens, and made it impossible to view the secret message. Well i didn't want to ruin a good card, so I finished it a little differently than expected.
