Childhood: One set, two pairs

[Time Out Tetris]
Do you remember "Tetris," which you and your friends would gather around and play during recess when you were a kid? Those were the happiest and most innocent times of childhood.
In the busy and stressful lives of modern people, we also long for a moment of respite, where time stands still, even if it's just for 10 minutes, to return to playing "Tetris" after class.

[Out Of This World]
Many people might remember seeing a very complex drawing in the past, where if you stared at it long enough, you could see a 3D image within it. These drawings work by shifting your focal point so that two adjacent, repeating patterns on the 3D image "appear" to overlap exactly, and the difference between the overlapping patterns creates a sense of depth.
In an era when computers and 3D movies were not yet widespread, this was a novel experience for children. They would often exclaim in surprise after seeing the image in the drawing, as if they could see another world.

#Flip-Over Sock Design

[Time Out Tetris]
The design features classic falling blocks on a black background. When the socks are folded down, some blocks are connected while others are not, just like life itself – imperfection is perfection.

The design uses alternating light and dark dots, crosses, and grids, creating a sense of visual confusion. The color used is a light yellow, representing innocent childhood. Additionally, the contrasting effect created when the socks are folded down is like stepping into another beautiful world.
