These are all pics I made months ago when the "hidden image" effect was just starting to be publicized. Highlight the pics or hit CTRL-A to experience the magic. Some of these may not be that good, I didn't bother to pic and choose the best ones, I just uploaded a batch from my hard drive.
Edit: Actually, the first one is not mine. Also, these all look better on a white background instead of this gray GFY background.
