Oppose While this is indeed one of the classic examples of an optical illusion, it isn't particularly encyclopedic.

The second example you cite is very effective at drawing in a user's attention to the topic. This (and the first FPC you cited) simply have no "wow" factor, do not look like they will interest the reader in exploring the topic further (than looking at the image for a few seconds), and are not encyclopedic enough to make up for it.

I would normally agree if the image wasn't an optical illusion. However, optical illusions aren't supposed to colorful or well-designed, it's the illusion itself which attracts readers to the article. This illusion in this case is certainly strong and becomes visible immediately. Michaelas10(Talk) 22:57, 8 February 2007 (UTC)reply
Oppose While it's very enc it doesn't have much else to speak for it. It's pretty much a 15 minute Photoshop job. ~
