Your brain cannot decide which way this horse is walking, and that is by design.
The “horse walking” illusion is a classic case of bistable perception, where the brain receives two equally valid interpretations of the same image but can only display one at a time. Because the horse appears as a high-contrast silhouette against a plain background, the brain gets no depth cues, no shadows, no texture, leaving it unable to determine which side of the animal faces the viewer.
No internet? No cellular signal? No worries—stay connected with a revolutionary new app.
Jack Dorsey, co-founder of Twitter (now X) and Block, has launched Bitchat, a fully decentralized, peer-to-peer messaging platform that operates completely off-grid, without needing internet access, cellular service, phone numbers, emails, accounts, or central servers.
Currently available in beta via Apple's TestFlight (and with an Android version in development), Bitchat leverages Bluetooth Low Energy (BLE) mesh networking to enable direct device-to-device communication. Nearby phones automatically form ad-hoc networks, relaying encrypted messages hop-by-hop across multiple devices—extending range far beyond standard Bluetooth limits through a "store-and-forward" system where messages persist locally until delivered.
This design makes Bitchat highly resilient: it shines in scenarios like internet blackouts, network shutdowns, remote wilderness areas, crowded events (e.g., concerts or protests), or even airplanes without Wi-Fi. All data stays on users' devices, with end-to-end encryption ensuring privacy and no central entity collecting information.
By turning everyday smartphones into a self-sustaining communication mesh, Bitchat embodies a push toward user-controlled, censorship-resistant infrastructure—an off-grid alternative to apps like WhatsApp that keeps working precisely when traditional networks fail.
While you slept last night, completely still in your bed, our galaxy moved millions of kilometers through the cosmos. You woke up in the same room, on the same planet, yet unimaginably far from where you were the night before.
The Milky Way is not drifting quietly through the universe. It is racing through space at around 600 kilometers per second, carrying billions of stars, planets, and everything on them along for the ride.
It is a good reminder that even when life feels motionless, you are always in motion.
