Ooooh, I like getting a hardware digital pet from time to time

Most recently, a
Bitzee, which is gonna be the protagonist of this post.
Those things blew my mind when I first saw them, they're essentially
holographic pets you can touch! 
I got lucky to find one at a good price, and I'm very surprised at how interactible they are!

Not only you can "pet" them, you can also
move the little machine in different ways to make them react.
They also have a lot of features - in fact, everytime I felt they could use something, it turns out they had. My version is the "fantastical animals" one, that has
20 collectable critters that go thru two evolutionary stages: some of them have "split" evolutions! Each fully grown version unlocks a minigame: simple ones, yeah, but I'm surprised
I can even play Frogger or Snake or an endless runner in this kind of technology (more on that later). It has a
"rotary" system in which the pets you already collected will call you to help them with something (they need food, they need you to clean their poop, another creature has messed them up and you need to solve their problems via magic, or they just need a good pat on the head). If you make three "care mistakes", the pet will go away (tho you can always bring them back and raise them from baby again); but I found this was
a good way to make you go thru your already collected pets. Sometimes get a bit annoying when I want to focus on raising one, but eh, can live with that

Hell, when it comes to features, you can even win potions on some of the minigames to change the pets' colours!
Yes, they have alternate color schemes!
What surprises me the most is
the technology used to achieve this. The "holograms" are made out of a little thing I call a "flappy screen": when you open the toy, it mechanically flaps, and the LED strip on top creates the image for your pet.
Given how this kind of technology works, I cannot recommend this digital pet to those who experience seizures or have frequent problems with eyestrain. 
I play it for short periods of time when my eyes are not tired, which is fine by me, lets me spread the game.
Okay, but the illusion creates this tiny pixellated screen, and the way the whole thing works fascinates me a lot because I see it as
both high and low technology. High tech because, let me remind you, THIS IS A HOLOGRAM TAMAGOTCHI YOU CAN PET. Low because all of this effort produces a tiny-ass screen with notable limitations, to the point this thing immediately teleports you to the era where you couldn't quite figure what the pixel art meant and you had to make up for it with your imagination (seriously, I still don't know what some of the obstacles on the endless runner game are

)
Overall? I love this thing. It's fascinating, engaging, and adorable. I read mediocre-to-bad reviews of this game over Reddit but that was from people who are die-hard Tamagotchi fans (no offense, I like Tamas too, I'm just in a Bitzee phase right now) who finished the whole game in two hours. And to those people I say, relaaax, it's best to savour games little by little
"Spoilers for a digital pet device"
I got one of the "split evolution" pets, an unicorn, and she gave me the item that would let me raise another unicorn. I bet this is intended so you can have both versions!
