Neuro Sandbox vs Antipode

Neuro Sandbox is an interactive visual sandbox for exploring neural network dynamics. Build small networks by placing neurons, connecting synapses, and observing how activity flows through the system in real time. Neuro Sandbox is designed for students, researchers, and anyone interested in computational neuroscience who wants to see how network behavior emerges from simple rules. Rather than writing code, you interact directly with the network. Adjust parameters, introduce feedback loops, and watch how excitation, inhibition, and decay shape firing patterns over time. What you can do: • Build custom neural networks by adding and connecting neurons • Assign excitatory or inhibitory neuron types • Adjust basal firing rates and synaptic decay • Modify synaptic weights and observe their effects • Visualize spike propagation and firing dynamics • Monitor live firing rates and recent activity history • Explore simple Hebbian-style learning rules • Detect and pause runaway network behavior

Ever wondered where you'd come out if you dug straight down, through the center of the Earth? Your antipode is the point on the globe exactly opposite to where you stand. Antipode pins your location, finds that point, and takes you there with a cinematic "dig through the Earth" navigation — through the crust, mantle, outer core and inner core, a 42-minute free fall to the other side of the world. INCLUDED • One tap to locate you and compute your antipode • Cinematic cross-section navigation through all four layers • Real physics: the gravity-tunnel trip takes ~42 min, peaking at ~28,440 km/h at the core • Home screen widget — your antipode, one glance away • Share a poster of your journey in one tap ANTIPODE PRO (one-time purchase) • Explore any place: search or long-press the map to find any location's antipode • Travel guide to the other side: flight distance, best season to go, nearby airports and towns • History and favorites: every antipode you've explored, saved • Four poster templates: Classic, Midnight, Magma, Minimal Only ~4% of Earth's land has land directly opposite — most people land in the ocean. Where's yours?
