Virtual Fish Tank
🐠💻 Project Idea Card: Virtual Fish Tank (Scratch)
🌈 What's the Big Idea?
Imagine your own peaceful underwater world — created entirely by you! In this Scratch project, you’ll design and program a virtual fish tank that’s more than just fun to look at — it’s a place that helps people relax, feel calm, and take a breather from the busy world.
This project is part of our Digital Changemakers series — where we use tech to make lives better, one sprite at a time! 🧘♀️🌊💡
🎯 What Will You Make?
You could:
- 🐟 Make fish that swim in loops, wander randomly, or follow your mouse.
- 💬 Click on a fish to reveal positive thoughts like “You’ve got this!” or “Breathe in… breathe out.”
- 🎵 Add relaxing underwater sounds or peaceful tunes.
- 🌿 Include seaweed that waves, bubbles that rise, or gentle light beams.
- 🧼 Create a “clean the tank” feature — drag the sponge around!
- 🧠 Add a timer so people can regulate themselves then get back to their busy lives
- 🪸 Let users add decorations like coral, plants or underwater castles
This project is all yours to imagine — solo or with a team. Build it, test it, then share it to bring calm vibes to others.
👷🏼♀️ Feature Cards (Build Your Projects Using These Features)
You might want to have a look at how to build the following features in your project:
✨ Simplify It!
Want to make it more simple? That’s OK! Here’s are some ideas:
- Use 1 or 2 fish that move across the screen.
- Add a calming backdrop and loop a short sound.
- When you click a fish, it says “Hi! You’re awesome!” 🐟❤️
- No timers or sliders yet — just art + motion + joy.
🚀 Extension Ideas
For those ready to level up:
- 🌎 Show facts about real fish and oceans — raise awareness!
- 🧪 Let players feed fish and see their moods change | can you get the fish to move to the food?
- 🧘 Create an interactive guided breathing fish that grows and shrinks gently.
🤯 Really Shake It Up!
Thinking outside the fish tank? Try these bold twists:
- 🧠 Build a Zen Tank: Instead of fish, add floating thoughts or clouds — users watch ideas drift by.
- 🧬 Code a "Fish Mood AI" — fish change mood if the user says nice or mean words to them.
- 🎮 Make it a Mindfulness Game: Users complete mini-games to earn new tank items.
- 🕹️ Add voice interaction: say “calm” to change music or “bubble” to add bubbles (using Scratch extensions).
- 🌌 Go Sci-Fi: Turn the tank into an alien aquarium with fantastic alien fish and other worldly plants!
❤️ Why It Matters
Everyone needs a moment of calm — and you can create that moment with code. Not everybody can keep living fish, and many find looking after them too much work - they would love to have a Virtual Fish Tank!
This project shows how computing isn't just logical... it's magical. You're learning how to build something meaningful that helps others feel good. That’s real-world tech power.
