What is this?
A living, breathing portrait of the Bitcoin network. Everything you see and hear is generated in real time from actual Bitcoin blockchain data, live from mempool.space. No simulation when connected: real blocks, real fees, real transactions. It reads public data only — no wallet, nothing to buy.
The valley
The neon landscape is network tension. When the chain is calm the valley lies low and open; as mempool pressure and block delay build, the walls rise and close in, your flight speeds up, and the music tightens from 72 toward 90 BPM. A ripple rolls down the grid on every beat.
The block on the horizon
The giant spinning ₿ cube is the next block being forged. Its glow tracks live network tension — ember when calm, burning when the chain is stressed. Gyroscope rings orbit it like a gravitational field.
Data absorption
Every small cube is a real network signal flying into the block — from above, eye level, and below:
Gold— a confirmed block: the big moment
Orange— fee pressure; count scales with next-block sat/vB
Green— mempool traffic rising from the valley floor
Blue— sudden activity bursts diving from the sky
Watch each one shrink and get swallowed — the block literally feeds on the network, brightening with every absorption.
The block moment
Roughly every 10 minutes a real block is confirmed: the cube erupts white-gold, twin shockwaves ring out, your flight surges, a chord stab lands, and the melody reseeds. No two moments are identical.
The music
Five live-data layers, each with its own toggle: Fees → harmony (chord brightness follows fee pressure) · Mempool → rhythm (drum density follows load) · Difficulty → mode (rising = brighter key, falling = darker) · Halving → drone (swells as the halving approaches) · Block → stab (the confirmation hit). Occasional high sparkle motifs drift over the groove. Untick any layer to isolate what the network is "saying".
Market & epoch
Live BTC price in 11 currencies with 24h change, sats-per-unit, the next difficulty adjustment estimate, and the halving countdown — all real, all updating.
The sky
Matrix code rain drifts through deep space (spot the ₿ hidden among the katakana), distant planets turn slowly overhead, and a moon keeps its quiet orbit — the calm cosmic backdrop to the network's heartbeat.

Reads public chain data only (mempool.space + price feeds). No wallet connections, no tracking, no custody. The ⚡ Tip button (Lightning/Liquid) exists purely if you enjoy it.
