Visual Sandbox Simulation vs Tessr

Browse through the library of realtime shader animations, adjust parameters on the fly and enjoy the show!

Tessr turns a group of phones into one giant, synchronized screen. At a concert, festival, or party, everyone opens Tessr. One person hosts, the rest join — and a single video spreads across all your phones at once. Hold them up together and it becomes one massive visual, like the LED walls at a show, built from the phones in your hands. And it's not limited to our library: sync a video you already have — a movie, a clip, your own footage — straight from your Camera Roll or Files. Your video stays on your device. No Wi-Fi, no signal, no problem. Phones connect directly to each other, so it works even where the network doesn't. Download packs ahead of time and light up the room anywhere. • Bring your own video — pick any video from your Camera Roll or Files and spread it across everyone's phones. Your video never leaves your device. • Tile mode — each phone shows one slice of a larger picture; together they form the whole thing, perfectly in sync. • Video packs — a growing library of visuals, from free packs to premium drops. • Friends & sessions — add friends by handle, and make any session public or friends-only. More phones. Bigger screen.
