AntColony vs Grumpy Grid

This app is an interactive simulation of ant colony intelligence. Tiny ants move through a graph of nodes and edges, following simple rules. As they travel, they leave pheromone trails that slowly evaporate over time. With no central control, patterns begin to emerge: paths strengthen, inefficient routes fade, and the colony gradually discovers the shortest way to transport food. You can change the structure of the world in real time: Adjust the number of nodes and edges Change the random seed to generate new graphs Move the food source and observe how the colony adapts Watch how collective intelligence arises from simple local behavior. No scores to optimize, no objectives to complete—just a living system you can explore, experiment with, and learn from. Perfect for anyone curious about: Emergent behavior Swarm intelligence Optimization and graph algorithms Complex systems made simple Sit back, tweak a parameter, and let the ants do the rest.

Tap. Bounce. Compose. Grumpy Grid is a musical playground where bouncing balls play your tunes. Place a colored ball anywhere on the canvas and it falls into a steady, perfect bounce on a row of musical pads below — playing a note every time it lands. Drop a few more, and a rhythm builds itself. No tutorials, no learning curve. The eight pads are tuned so anything you place sounds harmonic together. Drop balls higher for slower, sparser rhythms; lower for faster, busier ones. Stagger your taps to layer notes a fraction of a beat apart and you've got a loop. Made for play and for sketching: • Eight glowing color pads, each tuned to its own pitch • Snap to quarter, eighth, sixteenth, or eighth-triplet rails for tight grooves • Save and rename your sessions — every ball's bounce timing comes back exactly as you left it • Eraser for surgical edits; Clear wipes the canvas; Pause actually pauses time • Universal: iPhone in landscape, iPad in any orientation No accounts. No tracking. No ads. Nothing leaves your device. Tap, bounce, compose.
