<code>2024-08</code><br>
Code golf is the art of shortening a program as much as possible while still producing a required behavior. I made a tiny version of the quine, only 2877 bytes large. At the end it does render some random characters, but I still consider it valid. When code golfing, undefined behaviour is part of the fun.<br>

But to move right or down, it needs the bees own position to be picked by the engine, since the rules always extend right-down. That means when the engine picks the bee's position, there are <em>two</em> possible rules to execute. Therefore, moving right and down both have half the probability overall compared to moving up or left.<br>
