MOKIZEN — Create Living Worlds

MOKIZEN is a free web app for designing interactive 3D living worlds — planted aquariums, moss terrariums, paludariums and miniature landscapes — in the browser, with no install. You place plants, moss, stones, driftwood, lamps and fish in a 3D editor, watch the planting grow over a 90-day timeline, and share or remix worlds by link.

What can you build?

• Planted aquariums: iwagumi, Dutch, jungle and nature-style aquascapes with fish schools.
• Terrariums and wabi-kusa: moss landscapes, jars and bottle gardens.
• Paludariums and ripariums: half-water tanks with waterfalls and emersed plants.
• Miniature scenes: zen gardens, pagodas, bonsai and dioramas.

How does it work?

1. Start from a curated world, a text prompt (AI) or an empty tank.
2. Add and arrange items; lights cast real beams and colour only the area under them.
3. Check care needs in the species field guide and get a shopping list of what you used.
4. Share a link, export an image or video, or view it in AR.
