A little under 25 years ago, a particularly bizarre game was released for Sega’s Dreamcast. In actually, calling it a “game” might be something of a stretch. It was more of a pet simulator, where you need to feed and care for a virtual animal as it grows. Except rather than something like a dog or a rabbit, your pet is a talking fish with a human face that doesn’t seem to like you very much. Oh, and Leonard Nimoy is there too for some reason.

Most people in the world don’t even know this game ever existed, and frankly, their lives are all the better for it. But for those who lovingly cared for (or intentionally killed) one of these rude creatures back in the early 2000s, it’s an experience that sticks with you. Which we assume is why [Robert Prest] decided to build this incredibly faithful physical recreation of Seaman. 

The creature itself is a wireless animatronic that’s been fitted with several servos to operate not just its creepy human mouth, but its flippers, legs, and tail. [Robert] pulled the original speech clips from the game, and recreated most of the voice recognition prompts so he can converse with his pet monster. A Dreamcast controller is used to interact with the robo-seaman, but even that’s a bit of a hack. It’s actually just the shell of the controller which has been filled with new hardware, namely an ESP8266 and Nokia LCD that take the place of the original Visual Memory Unit (VMU).

[Robert] went the extra mile and also recreated the tank the creature lives in. The front glass is actually a transparent display that can show game information or “water”, and there’s sonar sensors that can detect when somebody has reached into it. The original game’s interactive elements involved adjusting the temperature of the tank and feeding your growing abomination, which are represented in this physical incarnation. There’s even little 3D printed versions of the bugs (which incidentally also have human faces) raise as food for the creature.

While this might not be our ideal office decoration, but we’ve got to hand it to [Robert], he did a hell of job bringing Seaman to life. Now let’s just hope it doesn’t escape its tank and get into the wild.

It takes but an ill-fated second to break a bone, and several long weeks for it to heal in a cast. And even if you have one of those newfangled fiberglass casts, you still can’t get the thing wet, and it’s gonna be itchy under there because your skin can’t breathe. Isn’t it high time for something better?

Enter Cast21, co-founded by Chief Technical Officer [Jason Troutner], who has been in casts more than 50 times due to sports injuries and surgeries. He teamed up with a biomedical design engineer and an electrical engineer to break the norms associated with traditional casts and design a new solution that addresses their drawbacks.

So, how does it work already? The latticework cast is made from a network of silicone tubes that harden once injected with resin and a catalyst mixture. It takes ten seconds to fill the latticework with resin and three minutes for it to cure, and the whole process is much faster than plaster or fiberglass.

This new cast can be used along with electrical stimulation therapy, which can reduce healing time and prevent muscle atrophy.

Cast21 is not only breathable, it’s also waterproof, meaning no more trash bags on your arm to take a shower. The doctor doesn’t even need a saw to remove it, just cut in two places along the seam. It can even be used as a splint afterward.

It’s great to see advancements in simple medical technologies like the cast. And it looks almost as cool as this 3D-printed exoskeleton cast we saw ten years ago.
