Family night
Crayons to the big screen
Kids color on paper, a parent snaps a photo with their phone, and the new fish swims onto the living-room TV.
Drawing together
Everyone draws at once
One kid on the tablet, another on a phone — every creation joins the same reef on the TV.
On the go
No TV? A laptop works
Draw on a phone and let a laptop be the aquarium — perfect for trips, rainy days, or grandma's house.
Party mode
A reef the size of a wall
Plug in a projector and turn a birthday party or classroom into a giant, glowing aquarium.
That's the whole setup
One thing to color on, one screen to show it. That's it.
