マジック・アイ：世界を見る新しい方法

My favorite way to unwind now is flipping to a random page and letting one of these hidden 3D scenes pop out at me. The solution key in the back saved me on the handful I genuinely couldn't crack.

It took me a few tries to get the hang of it, but the simple instructions really do work—once that first 3D image pops out, you'll be hooked. The solution key at the back is handy for the trickier ones.

The hidden 3D scenes are genuinely fun once you get the hang of it, and the viewing instructions on the first pages actually helped. I just wish the solution key was easier to flip to without losing my place. Still, a solid buy for a nostalgic afternoon.
