Read a value from each of the optic nerves present and write the correct value to the nerve that runs deeper into your visual cortex (V-CTX). To determine the value that should be written, count the number of values read that are greater than -55, multiply that count by 5, and then subtract 75. Repeat _ad infinitum_.

It is not necessary to leave no trace. Your EXAs should be written to operate indefinitely.
