I deeply resonate with this kind of physically interactive digital medium, some that immediatly came to my mind:

1. DIY live photo with Instax and tape that can be played in Califone Cardmaster (I've seen this in a Chinese video, you can search a lot of similar guides on YouTube)

2. Kazeta, the console DIY solution to let you play game by inserting TF card into a computer. discussed eariler here (https://dynamicland.org/) by Bret Victor.

We grew up before smartphones were ubiquitous, our digital experiences were tied to physical media. Cameras had film, Walkmans had tapes, VCD players had discs, and game consoles had cartridges. These objects are deeply embedded in our childhood memories, so seeing them today brings an inevitable wave of nostalgia and joy.

But it's more than just nostalgia. There's a tactile pleasure and a sense of accomplishment in using these physical items that a smartphone can't quite replicate. While phones offer immense convenience through countless apps, they also abstract away many opportunities for exploration and direct interaction with the physical world.

That's why, no matter how advanced our devices become—even if we one day have brain-computer interfaces—I want to preserve a culture of playing with and collecting tangible objects for myself and the next generation. My son currently uses a reading pen for his storybooks at bedtime. In the future, I plan to make him physical "launch cards" for music albums and games. These things serve as anchors, keeping us connected to the real world and preventing us from becoming completely immersed in cyberspace.
