Welcome to Follow-Up Friday!

By this time, you know the drill. Follow-Up Friday is a chance for us to revisit the subjects of previous posts and bring the PuzzleNation audience up to speed on all things puzzly.

And today, I’d like to return to the subject of optical illusions.

Puzzles for the eye, optical illusions challenge the viewer to shift perspectives and accept that seeing is not always believing. And whether it’s Ok Go!’s tricky music video or a carefully crafted LEGO illusion, they’re a favorite subject here at PuzzleNation Blog. I mean, heck, we’ve got entire boards on Pinterest dedicated to them!

So you can imagine my delight when I stumbled upon a CollegeHumor video that had some fun with a few classic optical illusions.

I present Optical Illusion Girlfriend:

Have a marvelous weekend, puzzlers and PuzzleNationers! Here’s hoping everything you see is what it seems. =)
