A generative pixel-art Walstad aquarium. Plants grow, fish school and breed, shrimp climb stems, snails crawl the glass. Watch a closed nutrient loop settle into equilibrium — chunky pixels, sim depth underneath.

walstad loom is a living tank you watch more than you play. A 3D voxel aquascape runs through a palette-quantize shader so everything reads as pixel art, while plants, fish, shrimp, and snails interact in a Walstad-style food web underneath.Stock a preset or build your own mix. Feed the tank, follow a creature, take photos, timelapse a bloom crash. The ecosystem self-balances over a few minutes — algae spikes when nutrients run hot, snails and shrimp graze it back, fry hide in the stems. Early access, very open to feedback and making this the best lofi-background aquarium experience possible.<h2 class="bb_tag" >Features</h2><ul class="bb_ul"><li>Generative Walstad ecosystem — plants, fish, shrimp, snails in a closed nutrient loop</li><li>Pixel-art look from a live 3D sim — palette-quantized voxel tank</li><li>Stock presets or build your own mix</li><li>Feed creatures, follow individuals, take photos, timelapse bloom cycles</li><li>Relaxing sandbox — watch equilibrium settle over minutes</li></ul>
