At the very beginning of Zork you are wandering through the forest. At one point, after branching around for a while you hear a bird singing above.<p>If you say &#x27;climb the tree&#x27; you read &quot;You are about ten feet above the ground nestled among some large branches. The nearest branch above you is beyond your reach.&quot;<p>If you &#x27;climb higher&#x27; you see &quot;On the branch is a small birds nest. &quot;<p>If you look in the nest, &quot;In the bird&#x27;s nest is a large egg encrusted with precious jewels, apparently scavenged somewhere by a childless songbird. The egg is covered with fine gold inlay and ornamented in lapis lazuli and mother-of-pearl. Unlike most eggs, this one is hinged and has a delicate looking clasp holding it closed. The egg appears extremely fragile.&quot;<p>If you open the egg roughly, &quot;There is a golden clockwork canary nestled in the egg. It seems to have recently had a bad experience. The mountings for its jewel-like eyes are empty, and its silver beak is crumpled. Through a cracked crystal window below its left wing you can see the remains of intricate machinery. It is not clear what result winding it would have, as the mainspring appears sprung.&quot;<p>If you wind it, &quot;There is an unpleasant grinding noise from inside the canary.&quot;<p>If you open the egg gently, &quot;The canary chirps, slightly off key, an aria from a forgotten opera. 
From out of the greenery flies a lovely song bird. It perches on a limb just over your head and opens its beak to sing. As it does so, a beautiful brass bauble drops from its mouth, bounces off the top of your head, and lands glimmering in the grass. As the canary winds down, the song bird flies away.&quot;<p>When I found that as a 7 year old, sitting in the dark after everyone in my family had gone to bed, peering into the screen of my 286, I knew that text adventures are the only game worth making.
