Drag the light around
The beam points wherever you last put your cursor, and the symbol inside it stretches as the angle changes, the way any projection does when it lands on something at a slant. Straight up it looks sharp. Swung out low across the rooftops it smears.
Leave the lamp off and you have a quiet city with bats in it, which is honestly the nicer version.
The bats keep loose formation
They watch each other. Push a group with the cursor and they split, drift apart, then close up again a few seconds later without being told to. Click over the buildings to add more. Fill the sky and it stops being atmospheric, which is worth doing once and then undoing.
What search actually gives you
Comic searches have picked up themed treatment on and off for years, usually around a release: artwork in the side panel, a tweaked logo, a small animation. Whether the batman easter egg google users remember is running depends entirely on when you look.
Every character tie-in works that way. Grogu google ran for a season, thanos snap for weeks. Rebuilds are the only reliable version.
