Description
# TROPICAL A live field on a mixing desk. Six cells on a side. The right-hand bars never sit still until the serial is right. The serial is 16 hex digits. The desk locks when the field holds a single height - not a password, not a checksum against a string in `.rodata`. Wrong serials keep the ground moving. Patching the lock bit is invalid. ## Run ./tropical Run in a colour capable, UTF-8 terminal. ## Goal Write a keygen. The unique serial is determined by the planted field, not by brute force. ## Hints The usual product is the wrong product. If a library offers you eigenvalues, ask which arithmetic it meant. Whatever lives in the serial is a height, not a point. One coordinate of the shape is already pinned; you are not searching a plane.
