Whale sharks drifting past. A quiet café after hours. Sixteen living worlds, just beyond your screen. Walltank — Let your desktop breathe. Whale sharks drifting past. A quiet café after hours. Sixteen living worlds, just beyond your screen. Eight grand aquariums and eight home & café tanks. Pick a view that feels like you. A gesture. A little connection. Rub your cursor back and forth to scatter food. Watch nearby animals moving that way gather to eat. Leave a little clearer. Algae grows gradually on the glass. Sweep your cursor across it to reveal the view, one patch at a time. From morning blue to midnight. Let the lighting follow your day, or keep your favorite hour. Place and style the clock right in Home. Made for your desktop. A native macOS renderer, layered scenery and still previews in Home. Music is there when you want it. Keep every color. Explore all 16 scenes for free with a text watermark. After 5 minutes, animals and scenery become silhouettes. Every Apply to Desktop restarts the 5 minutes. Remove Watermark removes the text and timed silhouette effects. One-time purchase · No subscription Optional Shadow Mode is included with Remove Watermark. Aquariums work offline. Radio, feedback, purchases and restoring purchases require a connection. These are fictional, artist-created scenes inspired by the ocean. Walltank is not affiliated with real aquarium operators.
