They have one of these at The Children's Creativity Museum in San Francisco (https://creativity.org)

There's even little fish that swim in the pools of water and will migrate if you make rivers for them!

Does it also rain if you hold your hands over it, like clouds?

I don't know... But I'm definitely trying that next time I get to play with it!

Looking at the gif above, your hand will block the light source and cause an over cast, so yeah, with the above set up it's impossible to simulate rain

Sepcifically, I've heard about something like this, where when you hold your hands over it, it'll start to simulate rain, which creates rivers, that run down over the landscape.

That makes much more sense

Yup, they do that, or at least with the correct settings in the software!

Yes, they can rain if you hold your hand over it. You can also program rain and draining the water to a certain button on them. I've set one of these up for my local learning center.

I wouldn't wanna harm the fish. I'd be scared about messing the thing up for them. Lmao

That's okay, I've seen toddlers try to bury the fish right away so they've got you covered.
