Every beat is a surge over stone.
Money was only ever the first thing to flow through a ledger like this. Deeds, shares, art, credit, identity — worth of every kind is headed toward tokenization, and once it's on-chain it moves the same way: continuously, measurably, in a current anyone can watch. Brük renders the current itself — its close cadence, its transaction volume, its network load — as real water over real rock. Faster closes quicken the current. Busier ledgers throw bigger water over the stones. Nothing here is invented; only the material changed.
How the water is telling the truth
The stream's flow rate and the shimmer speed on its surface track the real ledger close rate (bpm). A quick network runs a quick current; a slower one eases off.
Every close throws a surge over the rocks. Its height and the foam it kicks up are scaled to that ledger's transaction count against the rolling average — an average ledger makes a modest splash, a busy one throws real whitewater.
The network-load index (the old "temperature" reading) shifts the water from calm teal toward frothier, whiter turbulence as load climbs — same value, honest new material.
The stones are laid out from the real hash of a recent ledger — deterministic, not decorative. The same ledger would always carve the same streambed.
